Main a wholesome way of life can decelerate the genetic physique clock and add an additional 5 years to life, a first-of-its-kind examine has discovered.
The groundbreaking analysis discovered folks genetically predisposed to a shorter life improved their odds of survival by partaking in common train, a nutritious diet, getting sufficient sleep and never smoking.

In the meantime, folks with unhealthy existence have a 78 % elevated likelihood of early dying, no matter their genetic danger.
The examine additionally discovered that having each an unhealthy way of life and shorter lifespan genes greater than doubled the danger of early dying in contrast with folks with luckier genes and wholesome existence.

Researchers used polygenic danger scores to have a look at a number of genetic variants to reach at an individual’s total genetic predisposition to an extended or shorter life.
