The two most popular explanations of origin are that the belief goes back to pagan times when we believed in tree spirits, or that we are invoking Christ’s protection by referring to the wood of the Cross.

How to share your real-time location with Google MessagesYou can find the feature in the same place as the old one. To get to it, open a message and tap on the attachment icon on the bottom left. Instead of doing away with the current option, Google has split the "Location" feature into "Real-time location" and "One-time location" options.
