Why Humans become old?<span>Another prominent theory of aging is the telomere theory. The theory states that every time our cells divide the tips of our chromosomes called telomeres become shorter. Eventually, they become so short they stop our cells from dividing. This is knowns as the Hayflick limit, and as we cannot produce new cells, we age.
