When I was about 12 or 13 I had appendicitis. I was reminded of this earlier this week when I heard a talk about CT scans. Now the best practice to diagnosis appendicitis is to have a CT scan. Whereas 20 years ago when I had appendicitis the doctor push on my abdomen and said "does this hurt?" and then pushed on it again "does this hurt a lot?". The speaker was making fun of the way it use to be done, and everyone laughed, but it's true. That's why I got my appendix out. It hurt a lot.
