Why your dog isn't the age you think

Scientist measure age, by the amount of DNA cells that go dormant in the human body. As time goes by, more and more cells go dormant, which then the body has less cells to recover from damages of other cells to functioning cells and organs. mainly the largest organ on the body which is the skin.  Hence why the skin gets wrinkled or grey hair giving the impression that a person is old.  What really makes the body old is when the internal organs can't rejuvenate and recover because millions of DNA cells have gone dormant to repair the body of daily usage damage of the repairing cells.

This was tested on mice and pigs.  Its how a scientist found a way to increase aging in mice, and now those same scientists are trying to find ways to slow down aging in humans, by "rebooting" the DNA cells that have gone dormant and waking them back up.
It's just like rebooting a PC when it stagnates or acting slow. Same concept.
When waking up the dormant cells in humans, those DNA cells which are 'rebooted' then go to work in repairing the body and flushing out the damaged cells that are no longer of use to the body and create new cells in its place.
