We have to show you this thing. Well, 4 things. 4 things and a lizard. We blink more frequently than we realize, but our minds erase the darkness (yay, RadioLab), making us unaware of it. Based on averages (and we know you’re not), you blinked for 90 seconds of this episode. So if you thought you were safe, think again. $17.99 – $19.99
