“What makes me so certain that the natural human lifespan is far in excess of the actual one is this.
Among all my autopsies (and I have performed over 1000), I have never seen a person who died of old age.
In fact, I do not think that anyone has ever died of old age yet. We invariably die because one vital part has worn out too early in proportion to the rest of the body.”
– Dr. Hans Selye
