I took two years of college ASL just because I'd always been interested in it. I loved it, and secretly found it easier on my brain than spoken communication, even though it was a second language. Partway through my second year I was diagnosed with an auditory processing disorder. No wonder I feel like ASL conversations are a little easier for me - they ARE.
I joke often that if I could magically make everyone able to sign, or if that Google Glass project would work on developing captioning for everyday life, I'd have it made.
