our chromosomes all 46 of them are linear DNA molecules so they have ends to ends each chromosome and those ends need to be protected and those ends are called telomeres and good analogy it's like the hard piece of a shoestring exactly that's what an aglet is but as we get older they get chewed back and eventually they become so afraid that the cell recognizes the end of a chromosome as though it would be a broken piece of DNA and they shut the cell down trying to repair it and try to stick it together with another piece and you end up with a bunch of genetic chaos one thing that cells do to prevent from becoming a tumor as they shut themselves down and they become senescent and that's a whole other problem for the body once you've got a the zombie cell that's not dividing and is in panic mode but telomeres do a road as we get older so they've served as a pretty good clock
