so we can better appreciation it.(sic)
Being editing, grammar and spelling impaired is probably worse than being hearing impaired (bad joke, I know, but this totally deserves it! 'understand' or 'appreciate' would make more sense in this sentence!) but I have dodgy hearing myself. I can rarely understand what someone in front of me is saying to me if there is a lot of background noise (traffic, party-chatter, music, etc.).
The only famous hearing impaired person that I can think of right now is a woman who was in some FBI TV show and West Wing but I can't remember her name and I am about to (hopefully) go to bed and sleep or I would IMDB her - Marley Matlin?
