Donald Trump is not alone in bragging about how little sleep he needs, but why is sleep deprivation something people brag about, the Chicago Tribune asks.

In Springfield on Monday, he touted this trait, saying, “I have a great temperament for success. … You know, I’m not a big sleeper, I like three hours, four hours, I toss, I turn, I beep-de-beep, I want to find out what’s going on.”
