I don't think I really watch a lot of anime, and I read even less manga though I really love both anime and manga. I seem to go through phases. I'll watch a lot of anime and then totally stop as though I've forgotten about anime's existence... that's probably because I don't know what to watch next.
I began watching anime at a very young age, starting with Candy Candy, Fairy Florence, and My Neighbor Totoro. After that, I watched DBZ with my brothers, and then we scurried to find other animes to watch together. Nowadays I do the watching by myself which can be lonely, but my interests do diverge from that of my brothers, so it suits me fine =P
