i can't be sure because he's always been dense but I think he's in age related cognitive decline now - he can't follow/retain what his guests say.
this second guest is an easy guest, he's written a book about lumberjack culture and the myths and creatures loggers told stories about in the heyday of the lumberjack.
so the guest had just spent a few minutes describing how dangerous a job it was and many died - falling trees, axe blades, drowning - he finishes and Noory says 'I wonder if some of them were killed by falling trees and things like that.' GRAMPA HE JUST FUCKING TOLD YOU THAT!!!
he keeps doing it, the guest has addressed whether these creatures are myths, he said the fun part is considering if some of the stories are embellishments of real events/creatures because some of the creatures are similar to cryptids such as Big Foot that people today believe are real. But that doesn't get through the mush of Noory's mind, he keeps asking the guest 'are these real creatures or were they made up by the lumberjacks?'
