Survival skills
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
Hilton Hotema
In "Man's Higher Consciousness", Hotema wrote that man was designed to live 80,000 to 100,000 years, before his teeth and alimentary canal were subject to degeneration. It was published in 1952 as "Man's Miraculous Unused Power" using the pen name Kenyon Klamonti. George R. Clements (AKA Hilton Hotema, AKA Kenyon Klamonti) claimed he became a vegan at 9 years of age after reading a book about health at school. He said he lived as a breatharian-fruitarian for almost 80 years. He lived to 92 years of age." Hotema is documented in the book "The Struggle Between Religion & Science" by Marshall J. Gauvin.
