Why Do We Grow Old and Die?

Answer

We usually grow old and die because after a while, our cells stop dividing and replicating and simply die. This is because the end of each chromosome has a tip known as a telomere which is depleted causes the chromosome to unravel and cause death of our cells and by extension ourselves. This telomeres will usually wilt down to tiny nubs after 50-100 divisions a phenomena known as Hayflick limit.
