I thought for years that my problem in places where there were a lot of conversations, such as cocktail parties, going on was a hearing problem. Was extensively (read expensively) tested and I have only very marginal hearing loss at 67 (which I blame on my addiction to .32-20 and 7.65 Para handguns.....).
Turns out that I have some not-very-rare wiring/cognitive problem that causes me to only be able to focus on one conversation at a time; multiple inputs cause "jamming." OK, so now I do feel "special," but not better. On the other hand, I can't drink any more, so perhaps my liver has cured my brain.... "La vida es siempre tomar y dar" as they.
