What is "real" (biological) age?
Your chronological age is how many years you've been alive. Your biological age reflects how old your body acts based on lifestyle — sleep, exercise, diet, stress, smoking, alcohol and more. Research shows lifestyle can shift biological age by 10+ years in either direction.

The 4 habits that age you slowest
- 7-8 hours of sleep nightly — the single biggest lever.
- 150+ min/week of moderate exercise — walking counts.
- Don't smoke, and keep alcohol moderate (≤7 drinks/week).
- Manage stress — chronic stress measurably shortens telomeres.
