BioAge Standard · v0.1 invite beta

See your body's age.
Find the levers to grow younger.

YoungState estimates a composite biological age from sleep, diet, alcohol, exercise, smoking, body shape, and (optionally) standard blood biomarkers. It tells you which dimensions are most worth improving, and shows what your age would look like if you did.

Sleep well, age slower. Sleep poorly, age faster.

The most intuitive demonstration is the lever. Move sleep from 5 to 8 hours and your estimated biological age can drop 1-2 years. Sustained heavy drinking can accelerate your hepatic-renal system age by 3-4 years.

These estimates come from published observational research — they are population-level statistical associations, not individual lifespan predictions.
