These jobs don't pay enough to afford housing and food around here... It's done by older people who got their real estate when it was still cheap 10-20 (or more) years ago. Younger people have absolutely no chance of making enough to get by from this job. There's also huge competition on these jobs - older people who want to supplement their pension income, etc. I'm not averse to physical work (I like working on my grandma's garden, for example) but I'm afraid it just won't be enough money and that I'll have the same kind of problems... It's not just mental work I have problems with. In my downperiods I am unable to clean my teeth.
