What makes cells age? Wear and tear, yes. But biologically, says, Dr. David Sinclair, professor of genetics at Harvard Medical School, it’s lack of oxygen that signals cells that it’s their time to go. Without oxygen, the energy engines known as the mitochondria become less efficient at turning physiological fuel like glucose into the energy that the cells need to function. Eventually, they shut down.
