I surely hope that these cavers understand that "limb amputation" is one possible outcome. Speaking for myself - I would find that a teensy bit discouraging :-)

I only tried a squeeze cave move once in my life. I was a climber - but never a real caver (unless the caves were the kind you can stand up in). But once a group of climbers decided to go do a cave ... just for the heck of it. In the middle, there was one location where you had to squeeze through by lying on your back and contorting your whole body. I was the tallest and biggest person in the group. I made it halfway - and wasn't sure at all I could get thru. Even worse, I wasn't sure I'd ever be able to retreat back out ... if I kept going. I decided to bail out on that scenario - and managed to exit back to the cave entrance. Hahaha ! I guess you can say that I'm no serious caver. But I was not disappointed at the decision.
