So, some researchers in Africa decided it was high time to figure out how many hours of sleep wild elephants get at night because the ones in captivity only get four hours of sleep a night. They postulated that the wild ones got even less time. And were they right. The two elephants they tracked would sometimes go days without sleeping and when they did sleep they averaged two hours a night.
I could never be an elephant. I can barely function on ten hours of sleep let alone two.
