How long will I live? The weight of habits
No test can give you a date: longevity depends on genes, environment and luck. But decades of research show a handful of habits shift life expectancy enormously. Instead of an impossible prediction, this tool gives you something useful: which levers matter most for you — and how many healthy years are at stake.
FAQ
Can a test tell me when I'll die?
No, and be wary of anything that promises to. What can be estimated is the effect of habits on average longevity: a tool to decide where to act, not a prophecy.
Which factors weigh most on life expectancy?
Not smoking, regular physical activity, a whole-food diet, adequate sleep, moderate alcohol and strong social ties are among the most well-documented.
