Should I try to go to med school?

I've lurked here for a month or two now, but just opened an account. I hope it's okay if I ask a question that seems to get asked a lot. My question is whether you'd go back to med school if you were me? I'm 41, graduated from UC Berkeley, molecular and cell biology major, did all my pre-med prerequisites back then, 3.9 GPA (both science and overall GPA). I did some research in oncology as an undergrad and even had a small publication. When I graduated, start-ups and the internet in general... Should I try to go to med school?
