As for miso... it's kinda funny, but I'm quite deaf and hearing annoying noises is not one of my life's complaints. However, my wife's hearing is perfect as she can hear me thinking two rooms away. Fortunately, I have not been smothered in my sleep, given the number of noises a human body can make especially when sleeping, and her saintly tolerance of all my idiosyncrasies.
I have miso. AND significant hearing loss. It's truly what keeps me from probably going postal on someone due to the miso.
Completely off-topic (not that there is ever quite a "topic" in the Coffee House!"), but your comment about your wife for some reasons reminded me of a little story.
During the last several months of his life, my dad broke his hip and had to be hospitalized. Because of 1) his dementia and 2) his obstinance, someone had to be in the room with him 24/7 to keep them from "restraining" him, because he would CONSTANTLY pick at his IV and try to pull it out, or try to get up out of bed (usually because, if you asked him, it was "time to go home.").
So, we took turns and whoever's turn it was to spend the night could look forward to pretty much NOT sleeping.
I went in one morning to start my "shift," after my sister had stayed the night with him. I asked her how it had gone and she said:
"You see all those pillows? (there were about SIX pillows all piled up on the couch from where we kept getting nurses to bring us more) The ONLY reason we made it through the night is because I kept staring at those pillows, but I couldn't decide whether to smother HIM or ME."
