Anecdotal of course, but I had a friend who did this because she had picked it up from her mom. No idea why the mother did/does it though. –  BenCole Aug 23 '13 at 13:13

From my understanding, it's an anxiety response - a repetitive, absorptive activity that can be undertaken at any time in any place. Very soothing, but in a harmful way. As for why she picked it up from her mother? That's classic observational learning in children when trying to find a way to deal with a situation - in this case a genetic predisposition for extreme anxiety/panic. –  BenCole Aug 23 '13 at 18:26
