My superstition happens to be a healthy one. I always take stairs in a casino if possible. I sit enough during long sessions so a few extra steps coming and going works for me. I didn't realize it had turned from a good habit into a superstition until my last trip to casino. I parked on the 7th floor of the parking deck and felt obligated to walk the seven flights while entering the casino. I may be getting to old for my superstition.
