I started college when I was 41 yr, obtained my ADN at 47yr. I'm 56yr and work 7pm-8am 3day/wk in L&D. Sure I have ache but no more than my 20-30 yr old coworkers. Staff nursing is not the only jobs available for an RN. Dr office, clinics, home health care, nursing home, the choices are endless. You'll never know if you don't try. If you find it isn't for you what have you lost? Nursing school doesn't consist of only the younger set. Life experiences gave me an infinitely greater edge and confidence many of my classmates lacked. Go for it!
