I was thinking about this the other day.
Do you think the Appendix was a suicide mechanism. Just think about it, a long time ago they didnt have surgury so you just hoped you got better (like in stone age times). So if you got a blow to the abdomen powerful enough to puncture the apendix, chances are you've screwed up other things and probably wont live much longer. So would the appendix speed up the death so you dont have to suffer?
Remember I'm basing this on NOTHING.
