Okay so seriously this is something to worry about; I met a guy in university who was the salt of the earth, also very collected and always dressed neat and looking like he's ready for a business meeting at any time (guy came to university dressed in a business suit; although he was in his thirties, so he probably had a job anyway and that might be the reason); he disappeared for a while and then when he came back he was just dressed like an average university student and you got the sense that this man was dead inside. I found out from him that he was stuck behind someone in traffic back a while ago and honked for the guy to move. The guy came out and beat him near to death, causing him to bleed internally and requiring immediate surgery; the surgeon botched the surgery and damaged his colon (or maybe it was already damaged from the attack?) and he needed a second surgery; the poor guy now unfortunately needs a colostomy bag.
No one deserves to have something happen to them like this, but folks please be careful out there; some folks are just some of the worst humans and could ruin your life for nothing.
