Yes, started nursing school at 42 or so (can't remember how old I am sometimes); and graduated at 44. I'll be 45 now starting on a floor. Since I had many years at home w/ my kids and was able to take care of myself, I don't really look my age YET, or so many say.
In some ways it's an advantage. I notice the techs sort of pick on the younger new nurses, but they don't seem to look crossways at me -- I think they respect my age and station in life w/ three older kids, married 20 years, etc. I can also make great conversations w/ pts and understand their life experiences so much more at my age.
The physical part is hard. I get tired, but so does everyone else. It's tough sometimes to take direction and criticism (and be treated like a child) but "management" who may be 10 years younger than I am -- but that's the ropes. They did their time and they deserve the respect.
I'm happy I did it. I loved my former career, but got tired of cubicle life and full time hours, little significance in what I did. I know as a nurse I make a huge difference and effect people's lives everyday. Many will never forget me as their nurse . . . I'm also psyched for the future and all the options I have -- I can relax and be traveler, move w/ my husband, or get more edcuation and move into different specialities. It's great I think, once I get the hang of it all ...which I'm still working on!
Plus, if you DON'T go, all you'll be is 5, 10, 15 years older ANYWAY -- might as well go!
Heck, we had 60 year olds in our nursing class!
