Summary

You can’t stop the clock, but you can influence its rhythm. Aging is inevitable; accelerated aging is optional. Every healthy choice—whether it’s walking instead of scrolling, resting instead of overworking, or managing stress through breath rather than caffeine—tells your cells to conserve longevity. The science of aging doesn’t promise immortality; it offers agency. Your life span may be written in DNA, but your health span—how well you live those years—is written in how you live.
