Pursuing Rap's comment, I just finished a book mainly about Herbert Hoover, US president before Franklin Roosevelt. (It was interesting on many levels.)

His predecessor was Calvin Coolidge who ascended from vice president to president when William Harding died suddenly. He was the man of whom Alice Roosevelt, Teddy Roosevelt's daughter, said that he looked like he was weaned on a pickle.

Coolidge, Gene Smith, the author says, worked very little.   "Coolidge hardly worked at all; he napped in the mornings befoe lunch, dozed a bit after eating, lay down for a few minutes prior to dinner and then, in his formal attire, sat for just a little while before going off to bed."

Of course, it was also under Coolidge that the ground was laid for the stock market crash of 1929. He had been asked whether he was concerned that so many were buying stocks on margin and "opined" that it was not worrisome. In private, asked about it again, he said that he "thought even one dollar borrowed to buy stocks was too much but it wasn't for the president to say so."

So, evidently, a life of ease and rest does not necessarily make a man wise.
