Nobody ever has anything good to say about stress. It is right up there with mosquitoes on the list of the unwanted gifts from Mother Nature. Nevertheless, it is virtually impossible to live a stress-free life. We were designed to experience occasional stress and then quickly recover. Imagine you are a hunter-gatherer living 10,000 years ago. One day, things are not going well; and the creature you were hunting chases you up a tree. Very stressful. Once it stops growling, and wanders away, you climb down, cheer up and go merrily on your way. That is the kind of stress we were designed to deal with: occasional stress.
