I have a cold because germs are the only thing small children share freely 
a sore back/hips because I thought I'd be clever and go on the trampolines with the kids at the weekend and lifting said small children in and out of car/pushchair/high chairs
my period
but the cherry on the cake was sitting down with DS at bed time and bashed my head not once but twice (either side). I did cry into my Lemsip at that point 
Anyone want to share theirs?
