How much anime have you watched in all? Have you been keeping track? Can you at least estimate it within an acceptable degree of accuracy?
I'm trying to figure it up now, but it's kind of a long and slow process, eventually (within a few days I think) I may have a pretty accurate number of total hours of anime watched (that is, not counting the tons of stuff I watched as a kid on TV, there's no way I could remember all of that stuff to count that too).
I recommend not counting rewatches, just count up the total time of everything you've seen once, that's what I'm doing.
