The WSJ reports on a study saying that the best occupation is Mathematician, and the worst is Lumberjack. Furthermore, most of the top 20 jobs are mathematical.
The methodology is strange. It considered mathematicians to have easy jobs because they sit in air-conditioned offices all days and never have to use any physical exertion or breathe fresh air.
Mathematics requires more mental exertion than the other jobs on the list. I guess that they decided that mental stress is a good thing. Weird.
