We are no longer the body, mind, blood. We are at birth, or mid life, when we are old. This is why we die. I can say, if Einstein lived to now. His mind would be different from the mind he had when he was young and healthy. So, it seems we die because we lose what we are. If knowledge in the genes is discovered. We may find a way to stay ourselves (young/alive). I think this is not being considered in medicine right now ? Knowledge being our vitality. Is there any concept in medicine to keep the information contained in a young body from being forgotten, or experiencing entropy ? This is just conjecture. I don't know medicine at all. But what's your opinion on what I said ?
