Whoa dude, for your sake, I suggest you improve your English. Obviously you don't speak English in real life, but make some effort to improve it, yeah? xD If your bro's like you, then he should start improving too.

I've done some Google searches for you about this, deaf people can be accountants, chartered accountants, blah blah blah, deaf people can do almost anything a normal person can, except hearing, of course.

Being an accountant might just be a nice job for your lil bro.

It's not impossible you know...
