"...I've been stung by many a honeybee. I know I have no allergic reaction to them..."

Me too. But one day my partner and I both got stung, not the first time for either of us. Within about ten minutes his face turned red, started swelling up, couldn't breath, etc. I slapped some O2 on him and made a high speed run to the hospital, it took them about six hours to get him under control. He of course now carries a sting kit all the time, and so do I, just in case I (or my wife) should every have that first (and possibly last) allergic reaction...
