Telomeres are tasteful strands of nonsense DNA that decorate ends of chromosomes.
Each time a cell divides, a bit of the telomere is clipped off. Eventually, when the telomere is a mere buzz-cut stubble, the cell stops dividing. Some human tissues that divide indefinitely, such as reproductive cells producing sperm and eggs, contain telomerase. So do cells in embryos, but the telomerase gene is inactivated in most cells after birth. Reactivating telomerase could replenish lost cells.
