The rate at which people age varies significantly. While some individuals reach advanced ages like supercentenarians largely due to genetics, many lifestyle choices and behaviors can speed up aging. Stress, poor sleep, poor nutrition, smoking, and alcohol are some well-known factors. These environmental effects leave a mark on our DNA through a process known as epigenetics, allowing scientists to measure biological aging by examining the epigenome at key sites within our genetic code. In the past decade, scientists have developed various “epigenetic clocks” to track biological aging. These clo…
