I see a lot of threads about middle-aged posters wanting to become software developers but not really any on becoming a nurse. I have an undergraduate degree so would only have to go to nursing school. How many years is nursing school - 2? If only 2 I would be 70 when I finished. Would I be too old? I have a lot of energy so the workload would be no problem. But I only seem to see fairly young nurses. I have worked my whole life in the oil & gas industry and am ready for a change. I have always wanted to be a nurse. What do you think? Should I bite the bullet and register for nursing school?
