Aging is a complicated process. Beyond just looking older, aging also happens at a molecular level as your cells age.
Though there is a big environmental component to aging, your genetics can play a part too. Learn more with Nebula’s DNA test!
We curate personalized and easy-to-understand summaries of the most important studies on the genetics of aging.

The genetic theory of aging suggests that how long we live depends more upon the biological influences of genetics than external factors. According to this theory, lifespan figures are determined at conception by genes passed on by our parents.
It is based on the segments of DNA at the end of chromosomes called telomeres. These segments become shorter each time a cell divides. Eventually, they are so short that cell division cannot be performed without losing important parts of DNA internal to the telomeres.
Aging genetics go beyond telomeres and ultimately involve many genetic variations. For example, if you have a genetic variant that predisposes you to high cholesterol or high blood pressure, your overall lifespan may be shortened because of complications like heart attacks. Genes that predispose individuals to the opposite effects tend to increase lifespan, even if the person doesn't have the healthiest lifestyle.
While it is clear that genetics play a role in the processes of aging to some extent, maximum lifespan is most likely a combination of genetic and environmental factors. The strongest evidence for this theory is the seemingly species-specific timeframes of maximum lifespan. Getting a genetic test to determine your innate susceptibility can help you make plans to moderate other risks.
