Years ago my wife had me wear one with some special amulet to keep me safe, I always kept it inside my shirt as not to show off (dangerous in my opinion), Anyway, during a Songkran festival a bunch of mototaxis riders tried to get it away from me--guess they saw it on the back of my neck, resulting in a fight between myself and several of them. I ended up a little banged up but kept the chain. Lesson learned, I've never worn that chain--or any other again, especially now with the price of gold where it is, at the time I was mugged it was around 7k-9k for a baht of gold. So much for the amulet keeping me safe LOL!
