I have been reading this book My Big TOE, and there was this interesting part in there where the author was saying that science still can not figure out why people die of old age, well why the cells start to deteriorate. The author's theory is that people always put an expiration date on themselves, when in fact we have the capability to live much much longer! We could live until 500 if we never convinced ourselves and our cells that we expire at about 80.

What do you guys think about this? It makes sense. The feelings we have about our health and our bodies are relayed to our cells like commands. Anyone know how old the oldest living person was? I think a man in china lived to 175, but there is no evidence.
