One key factor in cellular health is telomeres, the “safety caps” that protect strands of genetic material within our cells.
As telomeres shorten, that genetic material will start deteriorating, and this will send a signal that the cell is growing old and will soon begin the process of cellular death.
The enzyme telomerase helps maintain the length of telomeres, but, as we age, telomerase becomes much less active, which impacts cellular aging.
