Functional age

Three tests. Five minutes. A number — without a needle.

Balance on one leg with your eyes shut, stand up from a chair five times, do push-ups until you can’t. Each one has been measured in thousands of people by age, and we place you on those curves.

• Single-leg balance, eyes closed
• Five sit-to-stands
• Push-ups to fatigue

You’ll need a chair without arms, a wall to stand near, and a floor. Stop any test that hurts. This is not a medical assessment.
