Friday FYI: Toothache Be Gone

How a Segway can make your toothache go away.

Reason #138 to stop hating on Canadians: in a 1980 study, they found a neat trick to make toothache go away without even parting your lips. All you need is an ice cube and a loser to sign-diss.

Fine, you don’t really need the loser — you just need to rub the ice cube on the V-shaped area that forms between your thumb and your index finger when you show that dude on the Segway just what you think of him: 5-7 minutes should do.

That V-shaped area contains the nerve endings of neurological pathways connected to brain centers that control the sensation of pain in the hands and face. Rubbing the ice cube on it helps block those centers — 90% of the study participants reported this technique helped nix the toothache. (The other 10% probably owned Segways.)

Nifty, eh?

GET A SONG UNSTUCK FROM YOUR HEAD

Blame your brain for that horrid Britney track stuck in your head since Monday’s morning drive — a glitch in your auditory cortex is causing the record to spin round’n’round endlessly.

Two ways to get it out:

1. Listen to the song in its entirety

2. Do some math

No joke, folks. This stuff works like magic.
