I’m 46. I can’t tell you hour long it’s been since I heard these terms. They’re completely unimportant outside of a very niche science (but, not entirely useless knowledge).

The stuff about Nutty Putty Cave plummeted my interest in caves to absolute zero (tl;dr caver ends up trapped upside down and his remains are still there and the cave has since closed, real nightmare fuel and not even the only cave it’s happened in).
