Disappointed that I'm still in my early 20s and I can no longer hear the really high pitched noise that certain electronics make.
On the other hand, I can never be blasted with loud high frequency note as a prank anymore.

My thermometer lets out a high pitched beep when it's done. I can't hear it unless it's close to my ear. Not sure if it's cause I have damaged hearing or what. I have to go by the blinking °F on the display. When it stops blinking it's done calculating.
