Just staying pretty much worm free and simple use of herbs to dissolve the rock and stimulate/cleanse the colon function should enable any human on the planet to live 100+ years old before they experience the first signs of ageing due to wrong diet, for the simple fact many people use to live well past age 100, 150+ living on sheep/pig/cow/bread/butter and rock filled water.....back before the day of mercury fillings and a local medical doctor.
AND YES, many old men smoked cigars daily and lived up to 100 years old when they had no dairy to clog their arteries.......
WITH just a little common sense and a few herbs, 100 should be obtainable by anyone that has not been too damaged by drugs and operations....
MANY have tried "fasting", vegertarian diet, restricted diet and never lived any longer than their neighbor that lived on cow and pig...because both ignored an education on parasites, stone, toxins and herbal use.
IT ALL works best as a total and complete program, but every program that ignores the rock and parasites is doomed to complete failure.
Those seeking diet pills and the next "exercise" truely are the most "lost" souls I can think of, caught up in the hype of advertizing.
