I'm 39 as of yesterday and FiM is the first MLP I ever watched. When I was young I watched transformers and got the toys (gen 1), G. I. Joe: A real American hero, and He-Man. I've always liked Loony Toons/Merry melodies (50's and early 60's). When I was older I liked animaniacs. When I was in my 20's I liked the simpsons, king of the hill, sailor moon and futurama (which I still watch). A few years ago i saw MLP:FiM for the first time and fell in love with it. I think you never get too old for cartoons.
