Jackets5-
I think your situation reminds me a lot of my own path to medical school. I got a phd and currently work in the patent field as i apply to med school this cycle. First off, like others have said, get exposed to the legal practice and decide if its something you want to do. I was seriously contemplating applying to both law and medicine after my phd since i really do find both fields fascinating. However, after talking to many lawyers and doctors and working in the legal arena for a couple of months here's what I found:
1. A LOT more docs were satisfied with their careers versus the lawyers and I have spoken to partners that were making huge sums of money with a corner office overlooking the park etc. etc.
2. When I asked if they would do it all over again, >90% of the lawyers wish they followed their hearts and went into something other than law whereas >90% of the docs said they couldn't see themselves doing anything else but medicine
These are my own experiences. Granted, a lot of docs wished they pursued other passions BEFORE medical school but they always said becoming a doc was the goal ...they just wanted to travel, pursue hobbies, etc. before 4 yrs of med school, residency, fellowship, etc. etc.
I will be 31 when I enter med school next year but I've finished my phd in o-chem, used my bachelors in business to intern in accounting firms, ran marathons, traveled around the world, work as a patent agent, etc. etc....you get my drift. Med school will always be there, don't be afraid to follow other passions - it doesn't mean that you're not going to be a great doctor someday just because you didn't want to be a doctor since you were a fetus and you had to follow the undergrad --> med --> residency --> fellow --> attending route!
Plus interviews are a lot more fun and interesting when you can relate stories from different experiences (I've been told by my interviewers!)
Best of luck in whatever route you follow!
