The one job i know for fact that i would never do is a builder in a skyscraper.
I do not care about the salary, i do not care about the work environment. All i am going to think about is the altitude. I have a serious issue with that and i get really sick, especially as the numbers go up! It does not matter how much money i will make because i will not live long enough to spend them on anything (of course having a family changes that, because i would provide them with something to live on comfortable and absent my presence).
