This is kind of a tangent from the article, but I wonder if this also holds for watching cute/small animals? My dentist has TVs that are almost directly above the dentist chair (so front and center when you are reclined, but not in a place you're worried about them falling on you) and they play this mindless channel that is just cute/small animals doing <i>things</i>. It is mesmerizing and time passes really quickly. If this study holds true, I wonder what other items on the spectrum of existence can reduce pain when we watch them.
Such a curious part of the human experience.
