We all want to live longer.
Correction – We all want to live longer, better, healthier, sexier, etc.
Well, according to researchers at McMaster University, we are wasting their time and money.
As published in PNAS, scientists took a group of mice that had been genetically engineered to age prematurely (due to a defect in a gene forÂ polymerase gamma (POLG1) that alters the repair system of theirÂ mitochondria) and by simply exposing them to 5 months of cardio training (45 minutes 3 x per week), they were able to put the brakes on their premature old age.
Even more science
Up until now, it has been thought that it is our lifelong accumulation of mitochondrial DNA mutations that leads to a cellular energy crisis which results in a progressive decline in tissue and organ function, ultimately resulting in aging.
These studies have been met with limited success,
But the mice in this “exercise as fountain of youth” study looked as young as healthy mice while their sedentary siblings were balding, graying, physically inactive, socially isolated and less fertile.
Get off the couch and go for a run.
