Getting sufficient rest is crucial for maintaining clear thinking and balanced emotions.

The text emphasizes the often overlooked importance of rest for preserving both our mental and physical health. Levitin disputes the false belief that as we age, our requirement for sleep diminishes, asserting that although our sleep patterns may change, the necessity for a steady amount of rest persists. The passage explores the vital role of sleep in reinforcing memories, regulating emotions, and maintaining a balance of different states of attention within our neural systems.

Insufficient sleep can lead to serious consequences for older adults.

Levitin warns that society's tendency to reduce sleep duration could negatively impact our health and well-being throughout our lives. He describes how continuous sleep deprivation, especially in older adults, can diminish mental functions, damage the brain's memory function, and increase the risk of obesity, depression, chronic inflammation, and various other serious health issues.

The author underscores the significance of even short durations of sleep deprivation, which can lead to severe consequences including a marked reduction in the brain's ability to clear out amyloid deposits linked to Alzheimer's disease. As we age, especially after we enter our fifties, it becomes more difficult to preserve consistent sleep patterns because of numerous factors that disrupt our circadian rhythms and hormonal cycles.

Strategies to improve the quality of sleep through modifications to an individual's sleep habits.

Levitin emphasizes the importance of adhering to healthy sleep habits that encompass a range of methods to ensure sleep that rejuvenates both our body and mind. He offers strategies for aligning our biological rhythms with the cycles of the natural world. This involves acknowledging personal sleep-wake tendencies known as chronotypes and arranging daily routines to be in harmony with these natural rhythms, which includes keeping regular sleep and wake schedules.

Maintaining regular and restorative sleep patterns is advantageous for people across all age groups, but it is especially crucial for older adults due to its profound impact on numerous health outcomes. Levitin explores the consequences of poor sleep habits and the age-related decline in melatonin, which can lead to a cascade of negative effects including diminished vitality and motivation, reduced social interaction, difficulties in recalling information, and an increased risk of developing dementia.

Forming social bonds serves as a remedy for feelings of loneliness.

This section of the book emphasizes the detrimental effects that solitude and the sense of being alone can have on our well-being, highlighting the importance of nurturing connections with family, friends, and the broader community to safeguard our mental and physical health as we age. Engaging in community activities is essential for sharpening mental sharpness, reducing stress, and cultivating a sense of purpose.

The influence of solitary time on one's psychological and physiological well-being.

Levitin emphasizes that extended periods of solitude in rodents can impair their dopamine reward system, resulting in a reduced capacity to experience the joy normally associated with social engagement. Moreover, these solitary rodents typically shun social engagement and frequently exhibit increased aggression and nervousness.

The author emphasizes the considerable health hazards that stem from being socially isolated and feeling lonely, likening their effects to those of smoking, and points out that these problems are often more common and difficult for older adults because of factors such as reduced mobility, moving on from professional life, and the loss or illness of close companions and spouses.

Cultivating and preserving robust social connections.

This section emphasizes the significance of developing and maintaining strong social connections, underscoring the necessity of nurturing our relationships and actively engaging in community activities to safeguard our cognitive well-being as we grow older. It promotes the pursuit of opportunities for meaningful involvement, nurturing and broadening one's network of relationships, and actively opposing any tendencies that could lead to social isolation.

Levitin underscores the necessity of actively seeking out social engagement and participation to combat the natural tendency to withdraw from communal environments. This could involve staying active, joining community organizations or even seeking therapy that specifically addresses social awkwardness.

Other Perspectives

• While the Mediterranean diet is beneficial, it may not be suitable for everyone due to cultural preferences, food intolerances, or allergies, and other diets can also promote health.
• Some experts argue that certain dietary fads, while not sustainable long-term, can provide short-term benefits or serve as a starting point for a more balanced approach to eating.
• The emphasis on physical activity might overlook the fact that for some individuals, especially those with chronic illnesses or disabilities, intense physical activity may not be feasible, and a more tailored approach is necessary.
• Aerobic exercise is highlighted for its benefits, but anaerobic activities like strength training are also crucial, especially in preventing age-related muscle loss.
• The concept of Embodied Cognition, while valuable, may not fully account for the cognitive benefits derived from virtual environments or sedentary activities that also stimulate the brain, such as reading or playing musical instruments.
• The importance of sleep is clear, but there is also a need to recognize that some individuals may have genetic predispositions or health conditions that affect their sleep patterns differently.
• While social bonds are crucial, it's also important to acknowledge that solitude can be beneficial for mental health and creativity, and not all alone time is detrimental.
• The negative effects of solitary time may not apply uniformly across different cultures or personality types, as some individuals may thrive in solitude or require less social interaction to feel content.

Aging is accompanied by physical changes and challenges, such as pain and the adjustment of our biological clocks.

This chapter shifts focus to explore how aging affects our physical sensations and the recurring cycles that regulate our bodily processes. The book explores the neurological foundations that influence how pain is experienced, which changes as one ages, and it offers strategies for its effective mitigation. The book explores the intriguing subject of our body's internal clocks, emphasizing how they interact with alterations in our sleep cycles, variations in mood, shifts in energy, and cognitive abilities as we grow older. The book offers a perspective grounded in science that equips individuals with the strategies to skillfully navigate the aspects associated with growing older.

Pain is influenced by a combination of biological, psychological, and societal elements.

This segment of the book delves into the often overlooked personal aspect of experiencing pain as one ages. Our perception of discomfort is profoundly influenced by our mental state, social environment, and personal experiences, and it encompasses more than mere physical sensations. Recognizing this complexity, Levitin dispels the myth that pain is an unavoidable part of getting older, and advocates for finding effective strategies for coping and finding relief.

Investigating the consequences associated with utilizing the Gate Control Theory in pain management.

Levitin explores advancements in pain comprehension by the medical community and researchers via the Gate Control Theory, illustrating that factors such as anxiety, fear, and distraction can amplify or mitigate the sensation of pain. He emphasizes the importance of brain function, noting that this new perspective has led to the development of improved approaches to pain management that include both medical and psychological therapies.

Levitin disputes the simplistic notion that pain should be avoided at all costs. The neural system responsible for conveying pain sensations evolved as a safeguard, signaling the presence of possible hazards in our environment. Individuals born with the uncommon genetic condition commonly called Hereditary Sensory and Autonomic Neuropathy, or HSAN, are unable to feel pain, a condition that can result in serious consequences for them. To effectively control pain, Levitin suggests that we should articulate and categorize it by pinpointing the particular type of sensation it invokes (like heat or pulsation), the emotions it provokes (such as distress or profound misery), and the mental evaluations we associate with it (such as being irritating or persistent).

As people grow older, they become adept at distinguishing the sensations of skin-related pain from the discomfort that originates internally.

The text categorizes pain into two primary groups: those that arise from the skin and outer areas of the body, and those that are caused by the body's internal components. A pervasive sense of unease within the internal systems of many seniors commonly remains undetected, leading to a shortfall in necessary medical treatment.

Levitin suggests that we describe pain differently depending on whether it comes from our inner viscera or from the external parts of our body. We frequently describe the feeling of touch on our skin using descriptors like pinpoint, sharp, and stabbing, whereas the language we use to express internal pain tends to be more emotionally laden and subjective, including words like persistent, pulsating, draining, or excruciating.

Maintaining our body's natural cycles is essential, and this can be achieved by aligning with our circadian rhythms.

This part explores the fascinating world of internal systems that govern when we sleep and wake, regulate hormone release, and influence the variations in our emotional and cognitive states. Levitin clarifies the processes that control these tendencies, dispelling the misconception that the elderly require fewer hours of sleep, and describes how shifts in our biological clocks with advancing age can significantly impact our health, overall wellness, and mental acuity.

The circadian rhythms' changes can significantly affect the sleep cycles, emotional states, and cognitive clarity of older adults.

The author explores the changes in our circadian rhythms that regulate our sleep-wake cycles throughout the aging process. These changes can play havoc on many aspects of our lives, causing insomnia, daytime tiredness, and changes in mood, alertness, and performance.

Levitin examines how the brain's primary clock, located within the suprachiasmatic nucleus, loses its capacity to consistently produce regular signals. With age, many people tend to retire to bed earlier due to a reduction in vasopressin, a crucial hormone for aligning the body's circadian rhythms, which influences their sleep cycles, body temperature control, and digestive functions.

Approaches to harmonize lifestyle decisions with innate biological cycles.

Daniel J. Levitin underscores the significance of aligning our daily routines with the natural rhythms of our bodies, especially as we age. He outlines numerous strategies that, if followed, result in substantial enhancements to mental and physical health by achieving restorative sleep. He recommends that readers recognize their own circadian rhythms and create positive habits that are in sync with these rhythms, such as choosing work hours that are conducive to them.

Levitin explores how the artificial blue light from devices such as smartphones and laptops misleads our bodies into treating it as daylight, resulting in a reduced secretion of melatonin that regulates our sleep patterns. The detrimental effects go beyond just interrupting sleep; they lead to an increased interference with the body's normal mechanisms for eliminating cellular waste.

Other Perspectives

• While pain perception is indeed influenced by a variety of factors, some argue that the biological component is the most significant and that psychological and societal factors play a lesser role in certain types of pain or in certain individuals.
• The Gate Control Theory, while influential, is not the only model for understanding pain, and some research suggests that pain management should also consider newer models that incorporate the complexity of the nervous system and pain processing.
• Categorizing pain for effective management is useful, but some critics might argue that this approach can oversimplify the experience of pain, which is highly subjective and may not always fit neatly into predefined categories.
• The assertion that older individuals can differentiate between skin-related and internal pain might not account for the variability in pain perception among the elderly, with some individuals experiencing diminished sensitivity to both types of pain.
• The idea that describing pain varies based on its origin could be challenged by the notion that language and cultural differences can also significantly influence how pain is described and perceived.
• While circadian rhythms are crucial for many aspects of health, some argue that individual differences in sleep patterns and needs can be quite significant, and a one-size-fits-all approach to aligning with circadian rhythms may not be appropriate for everyone.
• The impact of aging on circadian rhythms and the resulting effects on sleep, mood, and cognitive clarity can vary widely among individuals, and some older adults may experience little to no change in their sleep patterns or circadian rhythms.
• The role of the suprachiasmatic nucleus in sleep patterns is well-established, but other factors such as genetics, lifestyle, and health conditions can also significantly influence sleep as one ages, which might not be fully accounted for in the text.
• The recommendation to align lifestyle with biological rhythms assumes a level of control over one's environment and schedule that may not be possible for all individuals, particularly those with demanding jobs, caregiving responsibilities, or other constraints.
• The negative effects of blue light on sleep patterns are well-documented, but some research suggests that the impact can be mitigated by factors such as the use of blue light filters, the timing of exposure, and individual sensitivity to light.

Engaging mentally and socially remains essential with advancing age.

The book emphasizes the significance of keeping the mind active and sustaining social ties as crucial components for a fulfilling and complete life, highlighting the concept that our later years are not inevitably marked by decline or isolation. The book commends the continuous capacity of the elderly to make significant contributions to their environment, highlighting that their active participation in diverse activities, relationships, and communities enhances their mental and physical well-being.

Continuing to engage actively in tasks related to one's work is of great importance.

This section challenges the traditional societal narrative surrounding retirement. Levitin underscores the significance of engaging in meaningful pursuits, which can extend past traditional work, to preserve well-being throughout the twilight years of life. He explores the way work nurtures social connections and imparts a sense of purpose, both of which are crucial for a fulfilling and dynamic life.

Having a job can strengthen a person's feeling of having a meaningful role and enhance their connections with others.

Levitin disputes the traditional perspective that retirement signifies the conclusion of an individual's career. He argues that the preservation of mental sharpness, individual self-respect, and a sense of inclusion, as well as overall health, depends on engaging in meaningful pursuits and cognitive engagement, attainable through work or volunteerism.

Levitin explores the significant progress made when scholars from Stanford University engaged senior volunteers to mentor children facing economic hardships. The research revealed that individuals who volunteered had a growth in the size of their brain's hippocampal and cortical regions, typically linked with deterioration, in contrast to the control group who did not volunteer and exhibited a decrease in brain volume.

Engaging in volunteer work can greatly enhance a person's active participation and value to the community.

This section explores the significant benefits of participating in volunteer work to stay active and involved after concluding one's professional career. Levitin explores different programs that capitalize on the wisdom and accumulated experiences of the elderly, including Experience Corps, which places seniors in consultative roles within educational environments, and a community-based exchange system called linkAges, which fosters intergenerational service swaps, allowing older individuals to impart expertise in their areas of proficiency while gaining help with tasks such as shopping and transportation. He underscores the importance of these activities in creating shared learning opportunities and bridging the divide between generations.

Participating in volunteer activities contributes to preserving one's mental acuity and physical well-being.

Levitin emphasizes the many benefits that seniors receive from participating in volunteer activities, which not only bolster our communities but also preserve their feeling of significance, boost their sense of self-worth, and promote a feeling of accomplishment. Regular participation in social activities and interactions helps volunteers to focus less on self-reflective thoughts, which in turn reduces feelings of loneliness that can be associated with growing older.

Volunteering allows seniors to go beyond their individual experiences and offer their services towards a wider community goal, as described by Levitin. He explores a UK initiative called Befriending, which connects older adults with younger people to cultivate steady one-on-one companionship. Older individuals often feel less isolated, and younger adults learn from understanding the difficulties encountered by the elderly, which offers them important insights for their later years.

Engaging in ongoing education is essential for maintaining mental sharpness.

This part extols the advantages and delight of continuous education in maintaining mental acuity and engagement. The book encourages readers to embrace a perspective that highlights development, stressing the continuous opportunities for personal development and mental advancement well into our later years. The passage motivates us to engage in activities that expand our knowledge and challenge our cognitive boundaries, thereby nurturing curiosity, venturing into uncharted territories, and delighting in creative thought.

Participating in activities like arts and games typically involves socializing with other individuals.

Levitin encourages fostering a mindset dedicated to self-improvement as a strategy to counteract the often-resisted alterations associated with growing older. Engaging in the process of skill acquisition, which includes becoming proficient in different artistic techniques, understanding new computer software, and mastering the performance of musical pieces, is essential.

Levitin emphasizes the importance of pursuing new educational experiences to avoid becoming stagnant and to keep the mind active and engaged. Participating in thought-provoking conversations, nurturing an active social network, and dedicating oneself to lifelong learning can contribute to maintaining and possibly enhancing cognitive sharpness.

Building and Maintaining Relationships That Foster Growth and Connection

This section of the book emphasizes the importance of nurturing relationships that contribute to personal growth and happiness, underscoring the critical function of developing loving connections that not only bring happiness but also serve as a strategy to preserve mental sharpness as we age. The book encourages readers to forge connections with people who positively impact their lives, which paves the way for personal growth and the exploration of new experiences.

The positive impact of companionship and affection on overall well-being and physical health.

Levitin draws insights from the Harvard Grant Study, a thorough project tracking the life paths of many men for a period exceeding seven decades. Research underscores the importance of love and companionship in maintaining overall wellness and contentment.

Daniel J. Levitin emphasizes the significant influence that our relationships with others exert on our happiness. Nurturing affectionate relationships with family, friends, and partners is highlighted as the key to life satisfaction, outweighing the influence of health, wealth, or personal achievements.

Other Perspectives

• While engaging mentally and socially is beneficial, some individuals may find fulfillment in solitude or less social interaction, and their preferences should be respected.
• The ability to continue working or engaging in meaningful pursuits may be limited by health issues or socioeconomic factors, which can affect the feasibility of these recommendations for some elderly individuals.
• The emphasis on continuous work or engagement in later years may inadvertently contribute to the undervaluing of retirement and rest, which are also important aspects of a balanced life.
• Volunteering, while beneficial, may not be accessible or appealing to all seniors, and alternative ways of finding purpose and community should be recognized.
• The focus on maintaining mental sharpness could unintentionally stigmatize natural cognitive changes that come with aging, which can be a normal part of the life cycle.
• The idea that ongoing education is essential for maintaining mental sharpness may overlook the value of experiential wisdom and the diverse ways in which people learn and grow outside formal educational settings.
• The assertion that building and maintaining relationships is crucial for personal growth may not account for the complexities of relationships, which can sometimes be sources of stress or unhappiness for older adults.
• The positive impact of companionship and affection on well-being, while generally supported, may not account for individual differences in the need for companionship and the fact that some people may thrive as single or less socially connected individuals.

Wellness is bolstered and dignified aging is facilitated as individuals advance in years through a combination of theoretical frameworks, medical and technological strategies, and philosophical and qualitative considerations.

This chapter delves into a range of concepts and foundational perspectives that shape our understanding and achievement of dignified maturation, as well as contemporary medical and technological progress that may impact our existence and perceptions in our later years. The book explores the impact of individual perceptions of time on societal norms, emphasizes the importance of believing in one's capacity to influence the course of one's life, and considers the ethical aspects of advanced technologies created to enhance cognitive abilities. The chapter emphasizes the importance of individual happiness and defining what constitutes a satisfying life, and it integrates insights from scientific research into aging as we devise an all-encompassing plan for our later years.

The concept known as socioemotional selectivity. Our perception of time evolves as we grow older, and this change also affects our objectives and what we consider important.

This part delves into the theory proposed by Carstensen, known as Socioemotional Selectivity, which posits that a person's motivations for seeking social connections are influenced by their own understanding of the time they have left in the future. The theory posits that while younger people, who perceive they have plenty of time, focus on social objectives that are educational and preparatory for what's to come, older individuals, conscious of their limited time, give precedence to cultivating emotionally meaningful relationships and moments.

As individuals grow older, they experience a shift in their social motivations, leading to a heightened focus on the significance of emotional encounters.

Levitin explores the idea that individuals tend to prioritize emotionally rewarding and meaningful social connections as they grow older. In his view, younger adults often pursue social engagements that could enhance their career advancement or feel discomfort when alone, unlike their older counterparts.

As people age, they often experience an increase in happiness, which may be linked to a change in their social focus towards pursuing emotional fulfillment over the accumulation of knowledge. As individuals grow older and become aware of the diminishing time ahead, they instinctively shift their social preferences to engage in pursuits and form connections that bring joy.

A person's confidence in their abilities and autonomy significantly affects their ability to sustain self-sufficiency.

This section delves into the notion that an individual's belief in their capacity to carry out a particular task is associated with self-efficacy, and it further investigates the idea of agency, referring to the feeling of control over one's actions and environment. Levitin underscores the importance of these principles in living a rewarding life, especially when we face inevitable challenges that could compromise our independence as we grow older.

Encouraging self-reliance and proficiency in daily tasks.

Maintaining our independence and influence over daily tasks becomes crucial as we grow older, despite facing potential restrictions. Levitin outlines measures individuals and communities can adopt to bolster independence and reinforce the network of assistance for senior citizens.

Levitin demonstrates that straightforward measures can greatly enhance an individual's feeling of independence and value. He references research from the 1970s which shows that when elderly individuals in nursing homes were given the responsibility of looking after a potted plant, they not only tended to the plant but also showed increased social engagement and alertness, in contrast to those who were given a plant but told that someone else would take care of it.

Investigating the ethical implications associated with enhancing mental faculties and their influence on how we age.

This segment of the book delves into the ethical complexities linked to the employment of drugs and technological progressions aimed at improving cognitive functions such as memory and concentration, and it balances the benefits with potential risks. Levitin examines how these interventions might slow down the decline of mental abilities, while also highlighting the challenges due to the uneven access to these technologies, the long-term effects that are yet to be fully understood, and the potential implications for societal and ethical norms.

Examining the Potential Benefits and Risks of Pharmaceutical and Technological Interventions

Levitin delves into the ethical considerations surrounding techniques aimed at enhancing mental performance, such as the utilization of pharmaceuticals and the implementation of devices implanted in the brain that could sharpen cognitive abilities. In the future, people who do not have neurological disorders may use these techniques to improve their cognitive functions.

Levitin provides a careful examination of the potential harms and benefits of using drugs that have been shown to enhance cognitive abilities, such as Adderall, modafinil, Ritalin, and even nicotine. He cautions that while some individuals may experience increased focus and motivation from these substances, they also carry the risk of adverse effects such as addiction, disrupted sleep patterns, diminished creativity, and a narrowed perception that could lead to missing important events or details around them.

Evaluating and measuring the quality of life is essential.

The text prompts readers to reassess their definitions of a genuinely fulfilling life. Levitin examines the conventional approaches to assessing life quality, observing that they often fail to consider the distinct values that are important to each person. He emphasizes the importance of engaging in pursuits that bring happiness and satisfaction, recognizing that a meaningful life depends as much on finding one's calling, building relationships, and feeling a sense of individual achievement as it does on monetary success or achievements.

Individuals' perceptions of well-being compared to its measurable elements.

This section distinguishes the well-being that is affected by external factors such as financial status, physical health, or the presence of resources, from subjective well-being, which reflects a person's own evaluation of their satisfaction and sense of achievement in life. Levitin emphasizes the importance of valuing personal happiness over the mere accumulation of material goods or external successes, suggesting that a fulfilling life is built on achieving individual contentment.

The U-Curve of Happiness and its significance throughout the aging process.

Levitin explores the happiness U-curve, detailing the fluctuations in joy across different stages of an individual's lifespan. Studies on happiness suggest that while there may be a decline in middle years, it tends to rise as people enter and move through their fifties and later years. Levitin notes that this tendency arises from a shift in focus toward seeking meaningful experiences and valuing current contentment more than previous aspirations.

Levitin concurs that the observed U-shaped pattern is consistent with Laura Carstensen's concept regarding the selection of social and emotional connections as we age. As we grow older, we become more cognizant of life's limited duration, which encourages us to cultivate meaningful relationships and separate from those that lack fulfillment. He emphasizes that research consistently shows that people who dissolve their marriages in later years often find a degree of happiness similar to those who stay married, supporting the idea that marriage enhances a positive and optimistic outlook for men and women alike.

Confronting Mortality: Navigating Challenging Choices and Preparing for Future Care Needs.

The book emphasizes the importance of consciously considering one's later years, encouraging active participation in difficult conversations with loved ones, and assuming responsibility for future care planning decisions. Levitin emphasizes the importance of valuing the quality of our lives rather than merely their length and highlights the necessity of articulating our end-of-life preferences through proactive planning.

It is essential to discuss end-of-life wishes with family members and to put in place directives for future medical care.

This part of the text advises thorough planning for life's last phase to avoid burdening oneself or family members with difficult choices at times when we may not be able to make those decisions independently.

Daniel J. Levitin underscores the necessity for older adults to proactively plan for possible debilitating occurrences such as strokes, heart attacks, or the onset of cognitive decline. They may emerge gradually as time progresses. When such events occur, our family members and healthcare professionals are faced with difficult decisions about our medical care, life-sustaining measures, and the continuation of our lives, and Levitin argues that it is prudent to make these choices beforehand, when we are still in a state of clear thinking and not burdened by the stress that often accompanies emergencies.

The later stages of life are greatly enriched by the peace and comfort found in natural surroundings.

The excerpt emphasizes that the natural world can offer comfort and reduce suffering for those confronting terminal conditions in the twilight of their existence. Drawing on his medical expertise and personal anecdotes, Levitin illustrates how immersing oneself in nature can frequently induce a sense of peace and joy, particularly during difficult times.

Daniel J. Levitin illustrates through narratives of patients' experiences how the final stage of life can be enhanced in terms of comfort and quality, addressing both emotional and physical distress. An elderly patient in her eighties, overseen by Dr. Rachel Clark, suffered from an aggressive cancer that rendered her unable to communicate with her healthcare providers, causing her such distress that her only responses were to thrash about and produce anguished screams.

Other Perspectives

• While theoretical frameworks provide a structured approach to understanding aging, they may not account for the individual variability and complexity of the aging process.
• Socioemotional Selectivity theory may not universally apply, as some older individuals may continue to seek educational and preparatory social objectives, while some younger individuals may prioritize emotionally meaningful relationships.
• The emphasis on self-efficacy and autonomy might overlook the importance of community support and interdependence, which can also play significant roles in aging well.
• Encouraging self-reliance may sometimes inadvertently lead to isolation or neglect the benefits of communal living arrangements, such as assisted living facilities, where tasks are shared.
• The ethical implications of cognitive enhancement are complex, and there may be cultural or personal perspectives that view aging and cognitive decline as natural and not necessarily in need of intervention.
• The discussion on pharmaceutical and technological interventions may not fully address the societal pressures to maintain cognitive performance, which could lead to over-reliance on these interventions.
• Quality of life assessments often involve subjective measures, which can be difficult to standardize and compare across different individuals and cultures.
• The U-Curve of Happiness is an observed trend but may not be a universal experience; some individuals may not follow this pattern due to personal circumstances or cultural differences.
• Planning for end-of-life care is important, but the process can be emotionally challenging, and some individuals may prefer not to engage in such planning due to cultural beliefs or personal preferences.
• The idea that natural surroundings universally provide peace and comfort in the later stages of life may not resonate with everyone, as some individuals may find comfort in urban settings or within their own homes.
