Downtime takes its toll. But we didn't imagine how much it would be. A new study reveals that spending too much time sitting robs us no less than eight years of life.

Little exercise is enough - No excuse sticks anymore
One of the few consensus on fitness is that inactivity contributes to extra weight gain.
In turn, this excess waist can lead to obesity, cardiovascular problems, hypertension and diabetes.
So far the risks are well known, and many people resignedly accept them.
Now a new study includes huge damage to this account.
The research was done by the University of California at San Diego (United States).
In it, scientists have identified the impact of physical inactivity on chromosomes.
Samples were taken from 1,500 women, from which telomeres were analyzed.
These are the ends of DNA that shrink in size with advancing age.
As a result, the age marker was changed among those who did not meet the stipulated half-hour daily exercise quota.
Especially in women who spent more time sedentary - about 10 hours or more.
In this group, the shortening of telomeres totaled almost a decade of aging.
Clearly, it means that inactive women who spent more time sitting were on average eight years older.
This compared to other inactive women who spent less sedentary time.
But it is possible to observe the issue on the other hand.
This is because those who completed the 30 minutes / day at the gym revealed no association between idle time and telomere changes.
This suggests that physical activity may slow the shortening of the cells that comes with aging.
The study was published in the scientific journal American Journal of Epidemiology.
