I don't think you can bundle medical sciences and something like math/physics/engineering. To be a good doctor you need a good amount of analytical skills and intuition built on experience. But the most important of all is really, you need to have a lot of memory storing capacity.

Bulk of medicine is how much you can remember. There is nothing like, let me work this out on a paper or fire up a REPL, in fact in their case- Something like putting a patient on pause while you refer a book is totally unacceptable. So remembering stuff all around.

I realized this pretty early and decided not to be a doctor. I just can't imagine my self memorizing things at such detail.
