Tesla Believes a Man Might Live 200 Years

Tesla thinks a man has just so many hours to be awake, and the fewer of these he uses up each day the more days they will last. He says: "I believe a man might live 200 years if he would sleep most of the time. That is why negroes live to such an advanced age, because they sleep so much." In this Tesla doesn't agree with Tom Moore, who averred that —

The best of all ways
To lengthen your days
Is to steal a few hours from
The night, my dear.
