Large parts of Reddit are a creepshow, but I love this subreddit - "Today I learned".
F'rexample, today I learned that the victims of the 9/11 attacks, including people who fell or jumped from the twin towers, had their cause of death listed as "homicide from blunt trauma". Which is...weird but I suppose accurate. Murder with a blunt instrument, to whit an aeroplane.
Anyway, don't mind me - for some reason I'm obsessed with the 9/11 attacks at the moment. Wonky brain. But I'm sure other people have less gruesome factoids they've just learned and find quite interesting. Tell me them!
