Woke up in my bed after a really heavy night out at Uni (when I'd apparently been really badly behaved) covered in blood with a gaping wound in my neck. As my memory started to come back I had vague recollections of tripping up over something (probably my own feet) and falling neck first onto an iron spiked railing. I had an inch deep hole in my neck about 1 cm away from my jugular and got myself to hospital pretty damn sharpish. That was pretty scary given I had no recollection of it and could easily have killed myself and, coincidentally, it's the last time I got that shitfaced whilst on a night out. The only other one is when I nearly choked to death in a French restaurant when I was 10. Luckily my dad was there to do the Heimlich seeing as how my mum, sister and all the French people in the restaurant just kind of stopped and stared at me turning blue. He has since told he was only a few seconds away from grabbing a steak knife off a nearby table and performing an emergency tracheostomy (he's a surgeon so that's not as bad as it sounds).
