I think it's just one of those things that happen. Looking on the bright side if you ever become an astronaut then it's one less thing to worry about!

Our neighbours son had his appendix out and then the sister had exactly the same problem about a month later!

My brother-in-law had diverticulitis a while back - it's where a bit of intestine that used to go to the belly button still exists (Meckel's Diverticulum) and perforates or gets infected. They whipped out his appendix while they were in there "just in case".
