I just finished reading the link you gave me on Toxemia by Dr. Tilden. I did a little research and found that he lived to the age of 89. In his book he makes the following claim:
"Man is either the master of himself, or his appetite and sensual pleasures master him. If the former, he enjoys health until worn out; and he should go down at from
ninety to one hundred and fifty years of age. If he is inclined to the latter, yet has his habits more or less under control—is moderate—he may live from sixty to ninety years."
I have to believe that he was an incredibly disciplined man. So was he mistaken regarding the potential length of human life or the benefits of his lifestyle? I'm not saying that 89 years is not a full life, but I know people who throw caution to the wind and live longer than that.
