This is one of my favorite activities, and now it is scientifically proven -- "according to a recent study at the State University of New York-Albany" -- that yawning is good for you. It increases heart rate, cools the brain, and heightens attentiveness. Yes, it is a bit contagious -- and I'm sure you've already increased your heart rate, cooled your brain, and experienced a heightened attentiveness just by reading the word "yaaaaawn" -- but when it's a good thing for you, then that's a good thing.
Stay tuned, however, for a study from the University of Minnesota-Duluth which is racking up evidence that yawning is indeed bad for you. It's sure to happen.

Man...it works for dogs.
