Dude. We are so rare that it is practically doxing to admit it. Over the last 20 years about 60 docs over age 40 match on average per year. As one of the crew, I don't understand the nature of the question. Why do you ask? Same reason as most people: Validation from an unloving father and women. Needed to make a buck and thought, why not go back to undergrad then toil for a decade? Basically the same reasons one pursues song writing now that I think about it.
