Worry Beads can be very usefull to people who are hopelessly trying to stop smoking or want to reduce smoking.
Instead of lighting your favourite Marlboro, Camel or whatever, get your Worry Beads out of your front pocket and
start playing with them. I haven't tried it yet but i've heard it works. But their use is not just for relieving stress, in
Greece for instance it is very common to see people sitting in coffee shops talking, playing backgammon with their
Worry Beads in their hand, just because they feel like it. By the way their name in Greek is Koboloi.

I thought worry beads were those little beads of sweat you get (especially in Hollywood action thrillers) running down the temples of anyone in a tense situation...
