I was swarmed at about age 6 and stung at least 50 times(per my grandmother who counted). Normally that many stings can kill a child even though I'm not allergic. We were in a remote cabin in N.H. at the time and I was unlucky enough to be banging a tree with a stick. The tree just so happened to have a hive in it.
Of course they didn't take me to the hospital as I guess I didn't have any breathing problems. I don't remember this at all, which is probably a very good thing!
