    Interesting, never knew that. I’m in my 40s and can still hear the annoying high-pitched whine from the speaker outside a shop near me that’s designed to keep kids from hanging around.

      Ah, the “Mosquito” device.

      I have strong feelings on those things. Strong enough to drill holes in one while up a ladder wearing a visi-vest.

      Side note: It’s amazing how invisible you become while wearing a high-vis vest and a hard hat.
