Happiness and long-livers

With each year the long-livers are more and more. But is everything so smooth in their life. Are they friendly? The other day in Switzerland, with the help of eutonomy, the Australian scientist David Gudell committed suicide. He was 104 years old. He took this decision on his own. In his last interview, he said that he was bored with life, because he had not imagined anything. He was hungry ate and just sat till dinner and ate again. As the toon fell and could not stand up on its own, and so lay for a couple of days until they were found by relatives.
We are trying to prolong our life in every way. But nature is not deceived. Is it the happiness to be a weak old man and not be able to go to the toilet without help? Perhaps you should pay attention not to prolonging life but to self-restoring functions. As the dentist said, when asked why the new teeth do not grow. Because there is no germ for growth. There were two rudiments, for children's teeth and adults. And that's all.
No matter how long we did not preserve ourselves, we will not be able to increase our strength. And the old man will be an old man, and the young man will be good.
