What zombie cells? And how are they killing me?
My friend Mike sent me this article on "senescent" cells. These are cells that become inactive and stop replicating as the body ages. They don't die, but accumulate in your body and start damaging healthy cells around them. So they're called "zombie cells." Your body tries to get rid of them, but it can't get them all. Among many other ailments, they are implicated in the progression of Alzheimer's disease.
While science is looking for drugs and supplements to get rid of them, so far exercise seems to be our best weapon. Who'd have thought?
