An interesting question, DuneyBlues. I shall attempt to give my explanation on the matter in the context below.
I assume it is due to the fact that in general, mathmatics (or math) relies dominantly on abstract, logical and cognitive processing. From a personal standpoint, I have experienced numerous individuals who have either found the subject to be very comprehensive from the start, to laboriously difficult. I would speculate that it holds some genetic correlation with how the left hemisphere of a person's brain is structured? You know, gray matter and all.
I personally indulge in math as a matter of usual practice (wherein I encounter occasions of spare time), as I am conjointly interested in subjects that to a large extent rely on it, Physics and Visual C++ scriptwriting being two notable examples, so it is, as a requirement, to have decent math skills in order to interpret the other subjects, which are in themselves not math, but rely on it predominantly (the same applies for Chemistry, as well, as it is a Science subject).
Nurture and other environmental factors are both applicable to take into hand, as well.
