Why can’t I sleep?

 For as long as she can remember, Joanne Osmond has gone to bed at midnight and awakened around 3:30 a.m. Not restless. Not groggy. Wide awake, ready for a new day. Like others in her family, Osmond is a super-sleeper. For seven decades, she’s packed her prolonged days full of activity: as an adviser to small businesses, a member of her local school board, a state-level education leader, a Boy Scout volunteer, a church volunteer, a marathoner, a mountain climber, and a mother. “I’m not brilliant, I’m not a genius,” she says. “But I’ve had more hours in the day, so I could work harder than most people.”
