Polymath
"A polymath (Greek: πολυμαθής, polymathēs, "having learned much," Latin: homo universalis, "universal man") is an individual whose knowledge spans a substantial number of subjects, known to draw on complex bodies of knowledge to solve specific problems"
I like to think of myself as a polymath: almost everything interests me. I may have specialist knowledge in some specific areas, but above all, I like to know as much about as much as I can. Bringing understanding and knowledge from one area to solves problems in another gives me especial pleasure.
