LOL!! With my hearing - and luck - I’d be slammed by the train cuz I wouldn’t hear it coming unless I had my aids IN. I’ve worn my aids through maybe 1,000 or more airport x-rays - no problem. But YES, I always, always remove them for any kind of medical or dental x-ray just to be safe. And for sure if I was getting an MRI I’d tell the technician to write notes on a clipboard as my aids would be OUT.
I’ve also traveled with spare aids & batteries in my carry-on and checked luggage. Neither has seemed to affect the life or performance of either one.
So … picturing that MAD RUSH you have in the mornings … is it really SO crazy that you’d go without ears? Why not forego putting on your pants instead? Y’see how silly it is?
