I've been a nurse for a year. I was a little worried about the "Gaylord Fokker" Murse stereotype. That goes away quickly. Tons of dudes do it nowadays. I worked one night a couple of weeks ago when it was only me and three other guys on my wing. We got to leave the toilet seat up in the break room, and everything.
Advantages: No suit or tie, comfy pyjamas instead....Tons of young ladies in nursing school....Tons of young ladies working in hospitals....Three-day work weeks....The opportunity to travel, if so inclined (Travel nurses make mad money, and get a lot of their cost of living expenses paid for)....Unbeatable job security, don't have to worry about the job prospects drying up.
After I got out of my previous career, I retired for a year, figuring that I'd know what to do by the end of that hiatus (I had no clue). Another few months of casting about for something to do to pay the bills, and I got to talking to my sister. She's been an RN for about 3 years, and spoke very highly of the profession. It tweeked my interest enough that I fought the unmanly-seeming aura surrounding male nursing. Truthfully, as a single guy, I've found that when meeting new females in social-type situations, it's a huge plus. They see a guy nurse as caring, responsible, and all that other warm and fuzzy stuff. Plus, it seems that most ladies thought about a career in nursing at one time or another, so it's a good conversation topic.
