Our bodies are programmed to run down. A twenty year old man is already old and worn down in comparison with an infant. Similar comparison may be made of one who is sixty, who is ancient in comparison, with one who is twenty something. Life doesn’t mean a simple linear progression from birth having an open end.
Death is built-in, which is what the biological clock tells us. Each chromosome in a cell is packed to keep it from fraying and have ends: these ends are called telemia, and as cells divide and multiply to replace old and worn out cells telemia gets progressively shortened. In normal circumstances these telemia ends are only good for some 100 such divisions or so.
Life and death in terms of our biology teach us truth.
