Exercise is a natural antianxiolytic and antidepressant! A Duke psychiatrist once said at a conferance that if everyone ran/biked/aerobicised five days a week, it would be equivalent to taking 20 mg of Prozac a day( for those who don't have severe major clinical depressin that is.) I don't feel guilty at all going for a ride despite my numerous obligations. I figure it's cheaper than seeing a psychiatrist or paying for medicines every month.!
