So I guess “Pinocchio” wasn’t a documentary, because it got its facts totally wrong!
According to a new study out of Spain, when someone lies, the blood drains out of their nose, which makes it about two degrees colder . . . so it contracts.
That’s right, “Pinocchio” had it backwards . . . your nose slightly shrinks when you lie.
So where does that blood go? Your forehead gets about three degrees hotter, which means it gets bigger when you lie.
