How can I estimate and extend my lifespan?

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.

What is biological age?

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.

Resistance training · Resistance training is exercise in which muscles work against a load, such as weights, elastic bands or body weight, to build strength and muscle.
Muscle mass · Muscle mass is the amount of skeletal muscle in the body; it grows with resistance training and adequate protein and declines with age.
Grip strength · Grip strength is the maximum force of a hand squeeze, measured with a dynamometer and widely used as a marker of overall muscle strength and health.
