When I say BLINK! What do you think? 

Of that American POW who blinked the word “TORTURE” in Morse code live on Vietnamese television? 

Or do you think of someone with locked-in syndrome who can only communicate by blinking? 

Or do you think about the idea of a universal eye language that uses blinks?

Today on Audacious, you'll hear about all that, plus a headset that measures the blinking of long-distance drivers so they know to take a break, and what it’s like when you have a rare condition that makes it so you can’t stop blinking.
