Well, I am not young,42, and I am not old,80, so I guess i qualify to post about this. I am in Nursing school. I spent 21 years in the military, retired and then got a job as a police officer. I have realized that I do not want to help people in that fashion. I am so excited to start the nursing core (hopefully this December) and I am getting good grades in the prerequisite classes. I feel quite ready for this change and I know that I want it bad so I study hard. I think how good you are as a nurse depends on your maturity level, not age. I know many who are much older than I and would never be a good Nurse. I also know a young woman (26) who is taking classes and wants to specialize in Oncology because she had cancer and it was the nurses who helped her through that hard time. It comes down to this, why do you do your job? If it is to make a lot of money then get into stocks or investments. If you want to help people, be a nurse.
