Do you ever cross your fingers anymore?

I just wrote the phrase “Fingers crossed!” in an email to my editor. 

I used the phrase to signal that I was hoping for good luck, but when was the last time anyone actually crossed their fingers in real life?

I can’t remember the last time when I did.  Nor can I recall a time when someone crossed their fingers in my presence.   

Is it possible that the physical gesture of crossing one’s fingers for good luck no longer exists in real life, and all that is left is the verbal expression of the gesture?
