I did two years of studies in accounting and took a break from school. Now i'm looking to go back but i've considered changing my major to nursing. I Just turn 26 and was wondering if it's too late to consider a change to such a demanding field. I want to go all the way to specialize in Obstetrician/Gyneacology. Any advice will be welcome and appreciated. I love math, love some scince, but i'm fascinated with the woman's body and babies. Should i start in the next year or two, roughly how long will it take to complete considering i'm committed to it?
