““The problem began with his telomeres. What is a telomere? Picture the little plastic bits on the end of your shoelaces. Imagine each time you tie your shoes, you have to clip off a little bit of that plastic part to get it to go through the lace holes. After you’ve done this enough times, the plastic tip is gone and the shoelace starts to unravel. Once the laces unravel enough, it’s impossible to tie your shoes, and you walk around looking like a goober.””
