I guess its up to the individual, I've worn aids for over 50 years and go by the adage of use it or loose it. My loss was due to loud noise in my very early 20's. It has gotten worse as I age and seems to be fading faster now. I am to get a C.I. next Thursday on right side. Fortunately or unfortunately depending on where you set, it's all about communication. It seems that a lot of communication is done by voice so one is at a distinct disadvantage if one can not communicate that way. I guess simular to those that never learned to read. Many more opportunities open to those that are multi lingual and a distinct advantage to those that can sign and speak as well.
