They Stand Out From the Crowd - Nikola Tesla

Nikola Tesla, at seventy-seven the dean of American inventors, expects to live to be 140 by paying scientific attention to his diet. With a hundred triumphs of electrical engineering already behind him, he hopes to announce the discovery of a new source of energy and to produce steel twice as strong as that now available. He works incessantly in his laboratory, maintaining his vigor with two meals a day, the first consisting largely of fats for fuel, the second of proteins to rebuild the body tissues. He uses no coffee or tea, considers alcohol in moderation virtually an elixir of life, and does not mind being called insane because of his theories.
