Good for them!
I went to school in the 60-70's so there were no cochlear implants or even email back then.
Have a question for you now. How do the graduates fare in the collison or construction business? Since they cannot hear, they cannot hear warnings of danger?
I will find out for you and let you know! But to be honest, deaf people have strengthened their other senses so that they can tell something is happening without having to hear it. I think their peripheral vision is stronger.
i worked with a deaf guy who was a civilian for the Navy and our command would not let him go aboard ship to do repairs becuase they were concerned for his safety.
