You should read the book "The Miracle of Fasting" by Bragg. He discusses this quite a bit. Also read any literature about natural hygiene. Shelton is not bad as well. "Ask Barefoot" on curezone also agrees.

Also, look into Breatharians. Do a search on curezone. There are actually people (rare) who live off just water and sun.

I read an article somewhere detailing the bible and how it states how long we should live. Initially Adam and Eve were immortal. And then the time of Methusalah (sp?) he lived until 900ish. And then our lifespan was reduced to 450, then 200, and then 120 (those are not exact numbers and I don't have the article around). The bible says we are currently meant to live to 120. Experts today are suggesting the way the average american eats, our lifespan is going to get reduced to 50 or so (because toxic parents create toxic kids).

Anyway, I completely agree that aging is a sign of constipation (of the entire body), accumulation of mucus and toxins. Most people die of autointoxication, which causes diseases of many forms, whichever organ is the weakest link.
