He is a freak of nature. It's possible you have to be an athlete to notice it, but Trump is blessed with amazing energy, stamina and quickness (at least intellectual quickness), and he does not sleep very much. I noticed early on that in physical terms, and even in intellectual terms, he was a world apart from any politician practicing today -- and he is 72 years old. In this election, he is running day and night. It is Trump against hundreds of Democrats, and perhaps thousands of media types.
