Animals in nature live a life of a certain duration, and in natural conditions its duration is close to the “allotted” limit. The only exception is humans. Scientists believe that according to the law of life expectancy, its average figure should significantly exceed one hundred years. But in fact, the average life expectancy has not even come close to the hundred-year mark. But even with an incomplete life span, most people feel weak, suffer from various diseases, and are subject to mental degradation. Most schoolchildren are unhealthy, and many acquire chronic diseases at this age. Analysis of the iris of the eye shows that no one is in complete health. The fact of the unnaturally short duration of human life, often ending in dementia, indicates that there is something wrong in the habits of man's life and that there is ample reason for a movement for a great transformation of health.
