I'm not particularly superstitious but there is one specialised rule in the biker community regarding guardian bells. These are small pewter bells which should be hung low on a motorcycle to ward off road imps and breakdowns. Apparently the ringing of the bell causes any malignant road imps to fall off, and that is what causes potholes! Entertaining if far-fetched. However it is considered bad luck to buy one for yourself, it should always be gifted to you. I ignored this, bought one on a bike rally, hung it on my bike and returned home without mishap. However, after leaving my bike outside for about an hour, when I returned to her, she was dead as a dodo and wouldn't start again - dead battery - extremely unlikely after a decent run to keep it charged up! So maybe there can be something valid about some superstitions!
Ethical question - how do you feel about second chance??
