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.
