I was never a couch potato. Nor was I ever a jock. From my university days and onward, three days a week of lacing up my Nikes to pound the pavement, or three aerobics classes weekly, were enough of a workout for me.
I also had a serious problem with insomnia. It started out as trouble falling asleep. A bad day at work or excitement about an upcoming event kept me wound up at night and much too aroused to sleep.
