The registered nurses at your local emergency room can help out a lot. They do all sorts of different test to make sure you're healthy and that you are not in any risk. For instance, finding out you have cancer can save your life. At least for a little while if not for good. If we didnt have RN's or doctors, we wouldnt know and then you'd have no medicine to take or cures to try.
