Incidentally the only reason for me posting was Ed's comment about hearing impairment.
When I have more time I will read up on the genetics of hearing impairment- because I'm not sure about the truth of that statement- certainly it is true that more hearing impaired children are born of hearing parents, but I haven't had enough time to read whether that is simply due to sheer numbers, and I have other stuff I should probably be reading at the moment.
