Is there a lot of demand for people in these careers?

I think that it would be wonderful to have a career in one of the various healthcare fields. It must be so rewarding to be able to help people get better. Of course it must also be really hard to have to deal with it when people don’t get better as well. However, I think I might be interested in finding out more about the various healthcare jobs since I need to decide on some sort of career path and get started with the necessary training. I can’t live at home forever, and in order to move out I need some employment.
