When will I die?

Over the past 70 years, average life expectancy worldwide has risen by about 23 years. In many developed countries it is now roughly 78 years for men and 82 for women.

What drives that? Longevity is shaped by many things: genetics, chronic illness, habits, and environment. Research also links life expectancy to sex, diet, physical activity, BMI, stress, education, and income. Where you live matters too — health care access and quality vary by country. This quiz folds those kinds of factors into a rough, illustrative estimate — not a forecast you should act on.

Humans are keenly aware that life is finite. Most of the time we push that thought aside — yet we still wonder: “How much time do I have left?”

No quiz can answer that exactly. This one uses country-level life expectancy from worldometers.info, then nudges the number up or down based on your lifestyle answers — again, for entertainment and curiosity only, not as a real “death date.”
