I started medical school when I was fifty years old. It was something I had wanted to do since I was four years old.  At forty-eight, I went back to college to take all my pre-med requirements, and I got straight A’s. I took the MCATs, scored well, applied to forty-one medical schools and got four interviews. I was rejected by one, wait-listed at two, and accepted by the medical school that was my first choice. I remember when I first saw the envelope and it was thicker than the others, I started to cry.  I was the oldest student they had ever taken.

I graduated when I was fifty-four years old. 

This is an excerpt from a comprehensive interview.
