I ask because in his newest (about to be published) , science writer has a startling idea about yawning and true love.
"Yawns," Kean writes, in The Tale of the Dueling Neurosurgeons, "are a rich neuroscientific subject." Lots of animals yawn. Snakes do it. So do dogs, birds, turtles, apes, monkeys. It's a very old reflex; but in people, yawns can be contagious. We can catch them and send them. That's rarer. Only humans, baboons, chimps and (sometimes) dogs do that.
Who is going to buy that book? One article about it is enough, no need for 200+ pages.
