Too true. I didn't even work buildings that high (the highest tower is 105meters), but we had one new guy who was pale and sweating when he went over the edge of the 61m hight tower roof and ten meters down (so about 50m high) froze in terror for some weird reason and we had go down next to him and guide him down to the ground.
Never had any risky situation and plenty women would admire us swinging around and cleaning windows.
It sounds dangerous, but it's really not. Compared to being a teacher in the Canadian school system today, there is simply no contest. Kids can stab, beat, rabbit punch, throw chairs, bite, kick, smash things, drop rocks on your head, go mental, threaten to kill you, shove a pencil in your eye, slice you with scissors and you are not allowed to do anything back, business as usual. [All from 20 mins on Reddit] You are not allowed to fail them, talk down to them, hit back in any way, discipline or say mean things. My buddy wears Kevlar sleeves to work as he says that's where they bite and slice the most.
Tower's don't do any of those things.
You can get an IRATA or SPRAT in 2 weeks. If you want to be a teacher it's 6 years.[Canada]
