Aging is a fact of life. It’s inevitable. No more avoidable than finding a wet towel on the bathroom floor after your husband’s shower or running into someone you haven’t seen in 15 years when you’re rocking a struggle bun in your pajamas. But unavoidable doesn’t mean unalterable. Aging science clearly shows that, though you can’t change if you age, you can change how you age. Your health and longevity depend on a whole host of lifestyle and environmental factors that you are in control of. Browse our longevity series to learn more about the aging factors that you can control and the biology that makes them effective.
