Longevity Escape Velocity
Longevity Escape Velocity is the concept that one’s life expectancy would increase more than the passage of time by developing cures for age-related diseases. If a year was given, life expectancy would increase more than a year due to these developments. It was termed by Aubrey de Grey, a biogerontologist and well-known advocate of radical life extension. It is also called actuarial escape velocity.
Healthspan is the period of an individual’s life wherein one is free from illness, chronic diseases, and disabilities. Healthspan begins at birth and ends at a time when one is no longer healthy.
