Spannr / Glossary / Life Expectancy

Life Expectancy

Life expectancy is a measure of the amount of time an organism is expected to live.

Although the term life expectancy can be used to refer to a single organism, in most contexts it refers to an estimate of the average age that a population’s members will be when they die. Several factors can impact life expectancy such as year of birth, gender, location, genetics, and environment.

When measuring life expectancy, the most commonly used measurement is life expectancy at birth (LEB), which is a measurement of the amount of years, on average, a newborn can expect to live, if current death rates do not change.

 

Stem Cell

Stem cells, found in all organisms, are a type of cell that can replicate and replace damaged or lost cells.
