Longevity Genes Cannot Explain Why Centenarians Live So Long

A study of more than 1000 centenarians has identified 150 gene variants that are associated with a lifespan of over 100 years.

However, this genetic model cannot predict whether or not someone in the general population would live over 100 years. In fact, whether these gene variants play any major role in slowing the aging process remains unknown.

Food Consumer reports:

“Overall, genetics only accounts for 20 to 30 percent of a person's chances of living beyond 85 years ... And environmental factors such as diet and healthy lifestyle may play a major role in a person's longevity.”
