text: It is an old superstition, that when you make a statement, and then worry that, by having made the statement you've somehow jinxed it, you say 'touch wood'. \n\nEg, I think I've got the job, touch wood.\n\nOr, 'I think I did alright in that exam, touch wood!'\n\nThen, you should look around for a bit of wood to actually touch, to cement this!
