When I went to nursing school about 30 years ago, most of the people in my class were not just out of high school. I was 30 when I graduated (diploma program), but there were some in their 60's (who wanted to have the skills to take care of family members), and others of all ages and walks of life. Oddly enough, the economy for healthcare was in a turmoil back then, too, because a new insurance scheme caled DRG's had just come out, so few new grads were being hired.
I would say, go for it, as long as you can tolerate the physical demands. Most likely, your maturity and life experiences will work to your advantage, as will your business experience. In my case, I had an extensive background in science (chemistry) which helped me breeze through the science courses.
Don't forget that there are tax advantages to getting a lesser degree or diploma education first, and then going back for a BSN or MSN, if you want. If you get a diploma or ADN, you can get into the workforce quicker, and make money as you continue your education later.
Do you have any idea which specialty you might be attracted to?
If you would like to discuss this further with someone of the same age, please feel free to email me.
