I chose to become a nurse at age 31. I had no prior healthcare experience, and it had been awhile since classroom time. It was difficult at first, and come to think of it, difficult throughout. However, it has become very rewarding. Everyday you are challenged with new circumstances. You are always learning. There is never a dull moment.
So, I would recommend Nursing to anyone. However, don't do it for the money. Some people become so bitter, and angry. It's not worth being miserable over. kj
