It is 83 degrees in Aspen, Colorado—just hot enough that I started dreaming of ice cream as soon as I stepped off the plane.
Now, if I do find some ice cream and give myself a brain freeze while woolfing it down, I will have a better understanding of what that nasty cold-food headache is and how to combat it, thanks to this Scientific American video.
One of the things I like best about the video: Learning that, despite the ubiquity of the brain freeze, it’s still not 100% clear what causes it. In particular, there are several competing theories to explain why putting cold things in your mouth would make your forehead hurt. Nifty!
