Young Forever Summary The Biology of Aging

Aging is caused by interconnected biological changes, according to Hyman. These changes are influenced by our environment and lifestyle, and addressing their underlying causes can decelerate or even reverse them.

(Shortform note: In a 2002 article in Scientific American, gerontologists S. Jay Olshansky, Leonard Hayflick, and Bruce A. Carnes argue that while environment and lifestyle can influence health, they haven’t been shown to reverse the biological processes of aging.)

Next, we'll explain some core mechanisms of getting older and the relationship between systems, exposures, and biological age.

Core Mechanisms of Aging

Hyman argues that aging is a disease that impacts all systems of the body. This includes the microbiome, immune function, hormonal processes, metabolic and energy-generation processes, detoxification functions, the lymphatic system and circulation, and structural aspects.

Young Forever Summary Strategies for Living "Young Forever"

Hyman suggests using the Function Health's Young Forever Panel to assess your health. These assessments offer a foundational view of your well-being, interpreted differently from how a conventional doctor would. The majority of laboratory reference ranges come from an unhealthy population average rather than ideal levels for peak health. The Young Forever Functional Health Panel evaluates your test results using a functional medicine approach to offer insights based on ideal levels. The tests include a complete blood count, urinalysis, blood type, kidney function, liver function, pancreatic function, electrolytes, sex hormones, prostate health, adrenal function, autoimmunity, inflammation, metabolic health, cardiovascular health, thyroid function, toxin exposure, and nutritional health. They provide an essential health evaluation. They often cost more than $15,000, but a Function Health membership provides them for $499.

(Shortform note: While the Young Forever Panel offers a comprehensive health assessment, it’s important to consider the potential downsides of extensive laboratory testing. When you undergo a large number of tests, the likelihood of finding at least one abnormal...
