Thrive
Healthspan Predictor

About this calculator
This is based on your average habits over roughly the last 6 months.
It leans heavily on lifestyle: nutrition consistency, movement, sleep, booze, smoking, stress, and how much time you spend sat on your arse.
What it gives you
- Healthspan score: a simple 0–100 style score for how kind your habits are being to your future self.
- Expected healthy until: a playful estimate of how long you might stay reasonably functional.
- Start of decline: when the wheels may begin to wobble a bit.
- Verdict: because calculators are more fun when they judge you slightly.
