The Longevity Society

Healthspan is not a number you buy. It is four behaviors you can see.

Supplements, biological-age scores, and a new hobby every January are impressive. They are not a week. This Baseline is four boxes: strength, aerobic, sleep, daily movement. Check only when the thing happened. A blank is information. It is not a verdict.

Visible beats impressive. Pain that changes your gait is not a session.

I’ll send the Baseline.

One page. Four habits. Educational information — not medical advice, not a diagnosis, not a treatment plan. Talk odd patterns over with a clinician.

Free. Unsubscribe whenever. I will not sell you a number.

The four. That is the whole list.

Strength One session you can repeat. Leave two clean reps. Skip if walking changes.
Aerobic Twelve conversational minutes. No gasping. You should be able to speak a sentence.
Sleep window Same wake time. Lights out whenever you get there.
Daily movement Ten minutes outside. Shoes on. Back inside.

One safe progression per week. Not four new hobbies. Record the behavior — not a lab printout, not a biological-age estimate.

When you want the card you mark

The $9 Four Visible Habits Card is the same four boxes with a travel-week minimum and a recovery line for the days the body is loud.
