The ten-minute test

Seven things your chart never measured

Your age is on a form somewhere. How old your body actually performs is the number nobody ever gave you.

What you need

01A dining chair without arms

02A clear wall and a bit of floor

03A tape measure

04A timer — your phone will do

05One flight of stairs

What gets measured

Sit-to-standBalancePlank hold Waist to heightResting heart rate Step recoverySleep

No lab work. No wearable. Not one of these has ever appeared on a chart handed to you — and every one of them predicts how well you'll be moving in ten years better than the scale does.

About ten minutes. Stop any movement that hurts — skip it and enter your best honest guess. If you have a heart, joint, bone-density or balance condition, check with your provider before the stair test.

Then what

Hormone Optimization The conversation your doctor skipped. No single measure here isolates hormones — which is exactly why it gets missed, and why it sits underneath most of what you just scored.

Retest in 30 days One number, moving. That's the whole point — and the only honest way to know whether what you changed worked.

About this score

Each measure is compared with the typical result for someone your age, then converted into years and added up. It's a fitness and function estimate — not a laboratory measurement of biological age, and not a diagnosis.
