Are you superstitious?

I don't think I am. I won't hesitate to walk under a ladder or bother about a black cat crossing my path, but alway say "Bless You" when someone sneezes.  Also Although I'm not religious I've worn a St Christopher for at least the last 30 yrs, and have carried one in each car I've had for a long time too. One can't be too careful these days when out in one's car, can you?
