Presidential sleep troubles

How well do U.S. presidents sleep? According to the March/April issue of Mother Jones, a pair of past commanders in chief engaged in surprising sleep habits. William H. Taft, the 27th president from 1909 to 1913 and a sufferer of sleep apnea, was the nation’s heaviest president who, “rarely got a full night’s sleep and often dozed off in public.” In contrast, Calvin Coolidge, who served from 1923 to 1929, “was known to sleep 11 hours a day.” Maybe that’s one reason why he was nicknamed Silent Cal.
