At 64, I thought I might possibly be the old timer here...pass me the Geritol please.I hear that same sound when I turn my 69 year old head.....I guess my neck could use some WD40.
Probably goes along with what I hear when I step out of the bed at 2 AM to go pee....when I walk barefooted my cracking foot bones sound like I'm stepping on rice krispies!
