Hah!  A friend and former colleague (Bow R.) used to joke when someone yawned in a meeting: “Hey, now, no brain cooling here!”  Now I read that scientists think they've finally cracked the riddle of why we (and just about every vertebrate) yawn.  Yup, you guessed it: to cool our brains.

Bow, you missed your calling!
