On a healthcare cart

In my job I talk to a lot of men and women who have been nurse's aides or something other type of low skilled health care worker, the kind pushing a healthcare cart for a living. It must be kind of a drag to be around sick and injured people all the time, but I guess you get used to it when it's your paycheck. I'm sure some of the people I talk to were good at their jobs, and others I'm glad they're no longer doing it. The thought of some of these people being responsible for the healthcare of myself or someone I love such as my mother, is pretty scary. All of them are sick themselves in some way, which is why I wind up talking to them.
