Markismus, having been born into a family with deafness on BOTH sides (nerve-related on one side, age-related on the other), I can empathize with you. But even so, there are MANY MANY other conditions for which no amount of medication or intervention can guarantee quality of life. At least we have HAs to bridge the gap - and I’d say about 95% or more of us who recognize the need for aids and GET them benefit and enjoy higher quality of life.
All that said, the fact that both you and your brother are on the same path says something about a common environmental or genetic connection, I’d think? Have you both seen ENTs to rule out physical causes that could be fixed with surgery? If so, and you’ve been diagnosed with the kind of hearing loss that can benefit from wearing HAs, you’re lucky! The advances in HAs may seem glacial (compared to putting a man on the moon even), but they are ongoing. My Oticon Opn REI aids are better in some ways than the older Agil Pros - thanks to technology that allows better TV streaming and crisper high frequencies.
I TOO should’ve had aids at a much younger age - probably my 20s. But I didn’t have the money (and forget about medical coverage!) till I was in my early 30s. I’ve worn aids for over 30 years now, and have become comfortable with their benefits in hearing as well as ability to turn them OFF and utterly shut out all noise (if I’m doing something noisy, at a loud concert, or even just napping). You are smart to focus on the HOW. In time, aids will get better, but for now, there is no miracle cure for hearing loss - unlike laser vision fixes or even a pair of glasses that compensate for near/far-sighted situations.
Perhaps in my lifetime even there will be stem cell research or even inner ear hair replacement! If only I could get that Minoxidil waaaaaay down in my ear …!
