Ok Sam Pert you're on to something we here think about a lot. Some performers raise the hair straight up on our arms and back of our neck. I was tinkerin in my shop a few years back in total silence, my hair came up like i said. I felt someone was close by or watching and where i live that just can't happen. I slowley turned and a black bear was just sitting ten feet away pondering on me. There is no way i could have known she was there. When we come off stage some folks remark how we "rung em' out" crying and some relate the hair thing. Got to be something to it. Sixth sense is a good description. Cletus an Paw an 49 cats gets my hair up too if'n ya wanna know a'bout thet! But it ain't the same hair you bet!
