I'm 47, will be 48 in Oct. I graduated w/BSN this past Dec. I started Nursing School at 45. It was part of my career/life change (mid life crisis?) Anyway, I was treated like everyone else even though I was the oldest in my class at the time. I now have some great friends from Nursing School. Age is a state of mind. Don't be intimidated, just do it. If you wait and think about it more, you'll just be that much older when you start!
