Question 1

How can I estimate and extend my lifespan?

Accepted Answer

It depends on which factors matter most for you. Sleep, exercise, diet, smoking, alcohol, and blood pressure each shift life expectancy differently. A free quiz can estimate your lifespan and biological age in about 5 minutes, then show which habit would add the most years. YapSpan uses published study figures so you can see exactly where each estimate comes from.

Question 2

What is biological age?

Accepted Answer

Biological age is an estimate of how old your body acts based on health markers and lifestyle habits, as opposed to your chronological age (years since birth). Someone with healthy habits may have a biological age younger than their birthday age.
