25 years ago, I was co-habitating with a girlfriend and a number of friends. I was eating a pickled onion, and it just sort of slid down my neck, and stopped at around adams apple height. Too big to go down.
Wasn't hugely panicked,until I tried to breathe in...may as well been trying to inhale through saran...no biggie, I could do 30m underwater at the time, so had plenty of time...tried to exhale and no luck either.
Became a little worried, and did a quick assessment and realised that only a few tens of seconds had passed (if that), and there was another minute or so of consciousness to get stuff sorted (1:45 to 1:55 was my endurance limit back then)..all calm, and everything in slow motion.
Fingers in neck, couldn't vomit, a glass of water (????), swallowing all o no effect.
Was working out if I had enough time to leave my girlfriend a note, when I decided to ram my diaphragm into a breakfast bar bench...onion just slid out, and had the sweetest gulp of air in my life.
As a parent, one who has saved one from choking twice, I've always been worried about them alone.
Then this was sent to me today...and I want to spread it....
