We know that the human body can regenerate many of its cells, especially those worn by wear-and-tear, and those damaged by external factors and the environment. Our skin, for example, is continually replenished otherwise every tiny cut or injury will still be visible. Our blood is continuously renewed, to ensure that red blood cells are in the best possible condition for transporting oxygen efficiently to the rest of the body. And so on.
So, why do we age? It is simplistic to suggest that our bodies are somehow getting “old” and less able to renew themselves, although it is certain this is what is happening. However, what triggers the decline from a young body capable of continuous rapid growth and regeneration to an “older” and less efficient body over time is an interesting and very curious subject.
