My strongest memory of my appendix incident:
I was in my late 20's and I had some kind of attack. They sent me for a few tests and finally checked me into hospital for an appendectomy.
Okay. Fine and dandy.
I remember the doctor strolling into my room after the operation where I was all zonked out on drugs in the company of my ex.
Doc sez, all cheerful as pie, "Yep, it was the appendix was the problem."
Kinda didn't realize there was any doubt.
