you need to quit on that stuff, man, you can't fly
Seriously
As a man who afraid of heights I can tell that hypotheses doesn't work for me. I'm afraid of fall and I don't feel any urge to jump, only urge to runaway somewhere safeBut I only afraid when I can see the height below and if it's open air
I'm not afraid inside building or elevator
PS: I remember "funny" moments when I had to work on a 6 meter height having only half a dozen of two-by-fours under my feet and nothing else. You get used to it eventually, after you sweat through your bones![]()
