Liar, liar, pants on fire

There was an interesting and funny piece by Robert Krulwich on Morning Edition this morning, about the brains of compulsive liars. It turns out they have much more white matter than people who don't lie as much (and yes, we all lie). I wonder if storytellers, puppeteers and folks who do improv have more white matter as well. Not that we're lying--we're just making many, many connections on the fly.
