Myths and superstitions are sometimes fun to believe in. Nothing wrong with people believing in Sasquatch or ghosts as long as it doesn't hurt someone. Some people go a little further when they refuse to swim until an hour after they eat. Some myths aren't worth their weight in salt, whether you believe it or not.

There are dumber ones out there, but the one I, as an estate lawyer, deal with constantly is the idea that there needs to be a 'reading' of the will, where the family all gather and the lawyer reads it aloud to them for the first time. We don't do that; we just mail everyone their copy if they want it.
