However, the problem of some paramedics is exactly that: they do think about their work when they go home. They see a lot of unhappiness and can't shrug it off.

However, the problem of some paramedics is exactly that: they do think about their work when they go home. They see a lot of unhappiness and can't shrug it off. In that way, every line of work has its problems. The bottom line is: don't take your work home with you, unless it's also your hobby and your 'homework' is not just a continuation of your work. At home I do as much as I can in Scheme and Python, while at work I program Java. I'll be switching to a Ruby company soon and I'm not sure I'll continue doing as much Python at home.
