I think I'd just end it if I was slowly going both blind and deaf, that would be just too much.

I would go with keeping sight over hearing. Not having music would suck but I could deal with not being able to hear people as a lot of time I just want them to shut up. That would suck but I could deal with it.

I could deal with one or the other though if I really had too. If I went blind I'd just listen to music, read with braille, and talk to people. If I went deaf I'd watch TV and movies, read normally, use the computer, look at people, and talk to people through sign language.

Its strange that I've actually given this a lot of thought. For some reason I've always had a kind of irrational fear of going deaf and blind.
