Is there a way to slow down aging altogether?<\/p>\n\n\n\n<p>Though we don&#8217;t like to think about it, we&#8217;re all going to get old. But in <em>Ageless<\/em>, Andrew Steele contends that aging isn&#8217;t as inevitable as it seems.<\/p>\n\n\n\n<p>Read below for a brief<strong> <\/strong><em>Ageless<\/em> book overview.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-ageless-by-andrew-steele\"><strong><em>Ageless<\/em> by Andrew Steele<\/strong><\/h2>\n\n\n\n<p><strong>In his <em>Ageless<\/em> book, Andrew Steele argues that we can treat\u2014and even cure\u2014aging<\/strong>. He explains that with scientific advances that are already being tested, we can change the course of the biological processes that make us less healthy as we get older. He contends that one of the most consequential steps we can take as a society is to invest in science that will make longer, healthier lives possible for future generations.&nbsp;<\/p>\n\n\n\n<p>After earning a Ph.D. in physics at the University of Oxford, Steele determined that aging is the \u201csingle most important <a href=\"https:\/\/andrewsteele.co.uk\/about\/\" target=\"_blank\" rel=\"noreferrer noopener\">scientific challenge<\/a> of our time.\u201d So he shifted to computational biology, a field where researchers use large <a href=\"https:\/\/www.shortform.com\/blog\/multiple-data-sets\/\">sets of data<\/a> to understand the human body as a system. <em>Ageless<\/em>, published in 2020, is Steele\u2019s first book.&nbsp;<\/p>\n\n\n\n<p>In this guide, we\u2019ll examine how Steele defines aging and debunks common myths about what happens as we grow old. We\u2019ll also explore the processes behind aging. We\u2019ll then look at how we might cure aging with what scientists know now and with what they might discover in the future, putting the ideas Steele details into the context of the latest research in the field and comparing his predictions to those of other experts.<\/p>\n\n\n\n<p>(Shortform note: Experts don\u2019t agree on the extent to which <a href=\"https:\/\/www.statnews.com\/2015\/12\/29\/aging-disease-cure\/\" target=\"_blank\" rel=\"noreferrer noopener\">aging is treatable<\/a>, but many\u2014like Steele\u2014are optimistic. Some view the <a href=\"https:\/\/www.vox.com\/conversations\/2017\/5\/4\/15433348\/aubrey-de-grey-life-extension-aging-death-science-medicine\" target=\"_blank\" rel=\"noreferrer noopener\">body as a machine<\/a> that can run as long as we maintain it, and others predict that we\u2019ll use <a href=\"https:\/\/www.cbsnews.com\/news\/harvard-geneticist-george-church-goal-to-protect-humans-from-viruses-genetic-diseases-and-aging-60-minutes-2019-12-08\/\" target=\"_blank\" rel=\"noreferrer noopener\">DNA editing<\/a> to make the body immune to viruses and genetic diseases, and thus, we\u2019ll reverse aging. Conversely, some scientists <a href=\"https:\/\/www.statnews.com\/2015\/12\/29\/aging-disease-cure\/\" target=\"_blank\" rel=\"noreferrer noopener\">expect that we can\u2019t<\/a> cure aging because of the limits of our cells. And the idea that aging <a href=\"https:\/\/www.popularmechanics.com\/science\/health\/a43510158\/humans-can-stop-aging-but-not-reverse-it-study\/\" target=\"_blank\" rel=\"noreferrer noopener\">can be reversed<\/a> is controversial: Some experts assert that aging comes down to a thermodynamic process that\u2019s irreversible.)<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-is-aging\"><strong>What Is Aging?<\/strong><\/h3>\n\n\n\n<p>Though we all know on a basic level what \u201caging\u201d is, scientists often use common terms differently than the general public. In this section, we\u2019ll look at how Steele and other experts define aging. We\u2019ll also explore common myths that prevent laypeople and scientists alike from understanding aging as a process we can modify. Plus, we\u2019ll examine exactly what kind of future Steele foresees if we can intervene in the aging processes that make us less healthy and fit.&nbsp;&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-how-should-we-think-about-aging\"><strong>How Should We Think About Aging?&nbsp;<\/strong><\/h4>\n\n\n\n<p><strong>Steele uses the word \u201caging\u201d to refer to the process that causes our health to decline\u2014and our likelihood of getting sick or dying to grow\u2014as we get older<\/strong>. A key insight is that the diseases that kill us occur because of the aging process. Steele explains that age is the most significant risk factor for heart disease, stroke, dementia, and cancer, which we often think of as causes of death. He contends that because aging sets these diseases into motion, <strong>aging itself is the cause of approximately two-thirds of deaths globally<\/strong>.&nbsp;<\/p>\n\n\n\n<p>Steele explains that even if we don\u2019t develop heart disease or cancer as we get older, none of us are immune to the effects of aging. As we age, we experience more minor physical and mental changes that might not be considered diseases, but still reduce our quality of life: We get less physically fit, our health worsens, and our thinking and memory decline. <strong>Steele sees aging as a problem of human suffering<\/strong>\u2014suffering that doesn\u2019t have to be our fate.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-what-do-we-get-wrong-about-aging\"><strong>What Do We Get Wrong About Aging?&nbsp;<\/strong><\/h4>\n\n\n\n<p>Steele writes that a few mistakes in our thinking about aging prevent us from understanding how the process works\u2014or from realizing how much we can change the relationship between age and health. The first of these mistakes is to think that aging is inevitable. Steele argues that we don\u2019t have to age as we currently do. He explains that <strong>by studying the biological causes behind age-related diseases, scientists can learn to slow, reverse, or prevent them altogether<\/strong>.&nbsp;<\/p>\n\n\n\n<p>The second mistake\u2014which follows from the idea that scientists can study the biological causes of age-related diseases\u2014is that we fixate on diseases rather than on the aging process itself. Steele writes that we think of the diseases associated with age as separate processes, but they\u2019re actually set into motion by physiological changes that affect our entire body.<\/p>\n\n\n\n<p>Finally, a third mistake is to think that the goal of <a href=\"https:\/\/www.shortform.com\/blog\/curing-aging\/\">curing aging<\/a> is to live forever. Steele writes that <strong>the goal isn\u2019t to become immortal but to become \u201cageless<\/strong>\u201d by living healthier lives to the point that our risk of death won\u2019t be correlated with our age anymore.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-what-would-it-mean-to-cure-aging\"><strong>What Would It Mean to Cure Aging?&nbsp;<\/strong><\/h4>\n\n\n\n<p>The idea of increasing human lifespans is complicated not only on a scientific level but also on an ethical level. Steele admits that it quickly gets tangled up with questions about population growth, social inequality, and the environment. Yet he argues that <strong>the benefits of eliminating the suffering of aging outweigh the costs<\/strong>, thus making it important to increase awareness of scientific discoveries, make regulatory changes that shorten the path from lab to clinic, and allocate more funding to aging research.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-aging-is-a-consequence-of-evolution\"><strong>Aging Is a Consequence of Evolution<\/strong><\/h3>\n\n\n\n<p>Now that we know how scientists think about aging and what it might mean to make humans ageless, more questions arise\u2014perhaps most crucially: <strong><a href=\"https:\/\/www.shortform.com\/blog\/human-aging\/\">Why do we age<\/a> in the first place?<\/strong>&nbsp;<\/p>\n\n\n\n<p>All of human biology has been shaped by evolution. But if <a href=\"https:\/\/www.shortform.com\/blog\/natural-selection-in-evolution\/\">natural selection<\/a> favors traits that are advantageous, it\u2019s counterintuitive that we evolved to become less healthy as we get older. However, Steele explains that evolution involves tradeoffs. Aging evolved because <strong>evolution has favored our health and reproductive ability as young adults at the expense of health and longevity later in life<\/strong>.&nbsp;<\/p>\n\n\n\n<p>One theory about how this tradeoff happens is that because evolution doesn\u2019t have a mechanism for removing genes that cause harm <em>after<\/em> we\u2019ve reproduced, any genes or genetic mutations (changes to the instructions in our DNA) that harm us <em>later<\/em> in life continue to get passed down. Another theory is that the human body has evolved to prioritize maintaining its reproductive cells over repairing damaged cells, which leads to disease in old age.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-processes-that-contribute-to-aging-and-what-science-is-doing-about-them\"><strong>The Processes That Contribute to Aging\u2014and What Science Is Doing About Them <\/strong><\/h3>\n\n\n\n<p>If evolutionary tradeoffs that occurred tens of thousands of years ago explain <em>why<\/em> we age, then processes that happen in our bodies every day explain <em>how<\/em> we age. Steele writes that <strong>many biological processes cause the symptoms of aging<\/strong>. To figure out how aging happens\u2014and counteract it\u2014scientists need to understand these processes. In this section, we\u2019ve grouped 10 processes that Steele writes are characteristic of aging into three categories: the accumulation of harmful substances, the degradation of crucial systems, and the deterioration of structures and signals. We\u2019ll also explore the discoveries that Steele writes might shape future treatments.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-aging-process-1-harmful-substances-accumulate\"><strong>Aging Process #1: Harmful Substances Accumulate<\/strong><\/h4>\n\n\n\n<p>Steele writes that <strong>when substances that should be destroyed or recycled accumulate in your body instead, dysfunctions occur<\/strong>. Two materials that have particularly damaging effects as they build up are senescent cells and malfunctioning proteins.&nbsp;&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-aging-process-2-crucial-systems-degrade\"><strong>Aging Process #2: Crucial Systems Degrade<\/strong><\/h4>\n\n\n\n<p>A second process involved in aging is the degradation of important systems in your body. Steele writes that <strong>when processes become less effective with age, the changes can wreak havoc<\/strong>. There are three systems where this loss of effectiveness does a lot of harm: your stem cells, your immune system, and your microbiome.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-aging-process-3-structures-and-signals-deteriorate\"><strong>Aging Process #3: Structures and Signals Deteriorate<\/strong><\/h4>\n\n\n\n<p>A third process key to aging is the <strong>deterioration of structures and signals within and between your cells<\/strong>, which Steele explains plays a role in many diseases and dysfunctions associated with aging. There are five structures and signals that do extensive damage as they deteriorate: telomeres, mitochondria, DNA, epigenetics, and communications between cells.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-do-scientists-have-any-other-ideas-for-slowing-down-or-preventing-aging\"><strong>Do Scientists Have Any Other Ideas for Slowing Down or Preventing Aging?<\/strong><\/h4>\n\n\n\n<p>Many of the <a href=\"https:\/\/www.shortform.com\/blog\/causes-of-aging\/\">causes of aging<\/a> that scientists have investigated are isolated to specific kinds of cells or to one part of the body. But Steele writes that we need a more holistic approach to learn how aging works and how to cure it. By looking at human biology as a system, <strong>scientists will be able to build predictive models that show how all of the components work together<\/strong>.&nbsp;<\/p>\n\n\n\n<p>In addition to learning about human biology as a system, Steele contends that <strong>we may need to learn to modify our genes<\/strong>. He explains that genes seem to be responsible for only 10% of our longevity. But by studying people who have lived extraordinarily long lives, researchers could identify longevity-related genes and develop drugs to mimic their effects. Scientists could also use genetic therapy to modify our DNA by adding, replacing, or removing genes.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-can-we-prevent-aging-with-what-we-know-right-now\"><strong>How Can We Prevent Aging With What We Know Right Now?<\/strong><\/h3>\n\n\n\n<p>We\u2019ve discussed the advances that Steele writes may be able to delay or prevent aging in the future. Though much of that science is still in the research stage, he writes that scientists already have enough evidence to know there are things you can do right now to increase your chances of living a long and healthy life. Much of the advice in this section\u2014like eating a balanced diet or brushing your teeth\u2014won\u2019t sound novel. But Steele points out that <strong>we already have evidence that these measures are effective at keeping us fit and healthy as we age<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-quit-smoking-and-stop-living-a-sedentary-lifestyle\"><strong>Quit Smoking and Stop Living a Sedentary Lifestyle<\/strong><\/h4>\n\n\n\n<p>The first change to make is to <strong>quit if you currently smoke<\/strong>. Smoking increases your risk of cancer, induces DNA mutations, and causes chronic inflammation linked to cardiovascular disease. Steele explains that while smoking reduces lifespan by 10 years, quitting at age 30 restores life expectancy to normal.&nbsp;<\/p>\n\n\n\n<p>A second change that can impact your health is <strong>shifting from a <a href=\"https:\/\/www.shortform.com\/blog\/how-to-avoid-sedentary-lifestyle\/\">sedentary lifestyle<\/a> to a routine with daily exercise<\/strong>. That change reduces your risk of death and disease, boosts your metabolism, improves the condition of your muscles and bones, and reduces inflammation.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-eat-a-balanced-diet-but-skip-the-vitamins\"><strong>Eat a Balanced Diet, But Skip the Vitamins<\/strong><\/h4>\n\n\n\n<p>Another significant lifestyle choice is your diet. Steele explains that while it\u2019s difficult to conduct rigorous research, the healthiest option seems to be to <strong>eat a balanced diet of different foods, without an excess of sugar, fat, or alcohol<\/strong>. Eating less meat and more fruit and vegetables may improve health, according to Steele, and he contends that losing excess weight might reduce your risk of disease. Additionally, he notes that <strong>evidence does not support the efficacy of vitamins and supplements<\/strong> (unless you have a nutritional deficiency). Similarly, Steele advises against taking longevity drugs: We don\u2019t yet have evidence that the options available actually work.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-brush-your-teeth-and-get-enough-sleep\"><strong>Brush Your Teeth and Get Enough Sleep<\/strong><\/h4>\n\n\n\n<p>Steele writes that it\u2019s also important to <strong>brush your teeth twice daily with fluoride toothpaste and clean between your teeth<\/strong>, which impacts the population of bacteria in your mouth. These bacteria contribute to gum disease and to diseases throughout your body via chronic inflammation.&nbsp;<\/p>\n\n\n\n<p>Another important lifestyle choice is the amount of sleep you get. Steele writes that <strong>sleeping at least seven hours every night<\/strong>, but not more than eight hours, reduces your risk of death and enables your brain to flush out amyloids.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-take-precautions-against-infectious-disease-and-watch-your-cardiovascular-health\"><strong>Take Precautions Against Infectious Disease and Watch Your Cardiovascular Health<\/strong><\/h4>\n\n\n\n<p>Evidence is overwhelmingly in favor of taking precautions against infectious disease. Steele advises <strong>keeping up with vaccinations, washing your hands, cooking food thoroughly, and staying home if you\u2019re unwell<\/strong>. This can protect you in the short term by preventing infection and in the long term by reducing chronic inflammation.&nbsp;<\/p>\n\n\n\n<p>Steele also recommends monitoring your cardiovascular system. He writes that <strong>regularly measuring your blood pressure and heart rate <\/strong>can help you keep an eye out for signals you need to lose weight, get more exercise, improve your diet, or talk to your doctor.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-protect-your-skin-from-sun-exposure\"><strong>Protect Your Skin From Sun Exposure<\/strong><\/h4>\n\n\n\n<p>Finally, Steele advises that you <strong>protect your skin from the sun by wearing sunscreen, avoiding exposure when the sun is high, and blocking sunlight with clothing<\/strong>. This prevents the DNA damage that occurs when UV light breaks bonds between molecules. When your body repairs this damage incorrectly, mutations occur and cancer risk increases.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What&#8217;s Ageless by Andrew Steele about?
