Whew . . .
HbJ, maybe you should have put a age limit on this, us older guys can go on and on . . . . So I mention just a few things:
The latest: In 2007 I went over the front of the bike, going down a hill in the forest on the way from the lab to home. I know only that the bike hit something on the dirt road. I was lucky as I only got several bad bruises and the right eye had a different focus then the left for several months (a very strange experience).
An accounter with a rattler left me with a scare only. During a hike high above Ashcroft near Aspen CO, I heard the rattle quite close, then saw only part of the snakes body (never saw the rattle) scurry away from me, apparently they are quite shy when a little more than a meter away.
Last rock climb in the foothills south west of Denver: I helped a friend who had gotten stuck about 5 m above ground. Got him to reshuffle his feet and hands, but then I stepped on a loose rock, somehow I headed down head first. Just about only two meters above the ground my leg got cought on a tiny tree (the only one anywhere near) such that I was hanging there with my knee, head down. Had a few nasty little skin laceratins, that was all.
In Boulder, CO, as PhD candidates a lot of us did quite a few Diels-Alder reactions in glass pipes. After filling and cooling in a Dry Ice slurry, they were flame sealed, then allowed to come to room temp. before placing them in a heater in a special room. One time while warming to room temp. in a hood next to my working bench my sealed glass pipe blew (fault in it?). I heard a pice of it whistle past my head. Inspection showed that a Vigreux column which was hanging next to the pipe had its center section blown away, looked like someone cut it out smoothly. Most of the parts were cought by the window of the hood.
We also handled lots of benzene, pyridine, hexane, etc. with too little respect. It is possible, though, that some chemicals caused my polycythemia vera.
Cars: Got away with minor injuries, but creamed several cars.
