So what’s a telomere, you’re most likely wondering? Well, the scientific answer is that they are the caps at the end of our chromosomes that protect our DNA. Chromosomes carry all a cell’s genetic information and telomeres are the protective buffers that determine how fast they age and die. In layman’s terms, telomeres are like the plastic tips of shoelaces. If you lose the tips, the laces start to fray, rendering them ineffective.
