There must be a balance between everything.
I remember something on tv, some special "Look at how they survived this event" show. The guy got a nail driven through his head, or something like that, and then afterward was much more "aesthetic" and begin doing artwork of horses. Basically the same person, but a complete change in termperment -- Businessman to artist.
Thinking about it more, in some ways, I think I've felt better when I've had the flu.
