Train your face with a DS?

Nintendo has just announced that they will be doing a camera add-on for the DS, although I'm quite confused by the idea behind the first 'game':

Otona No DS Kao Training, or Face Training, includes a camera that plugs into the Game Boy Advance slot on the Nintendo DS and videos your face as you play the game. The idea is what the Japanese call "facening," or facial exercises. By doing certain facial exercises, you can make your skin more elastic and have a prettier face, or so goes the theory.

Ok..... moving swiftly on....
