Of course, we often think we have to get sick literally in order to get the rest or pleasure we need in our lives. Bobbie and I therefore taught our children when they were younger that if they needed a day off from school, they should just say that and take a health day, not a sick day. That made them look at life differently. I think all of us need to rethink our attitudes toward health and sickness.
