If it's true that a forced smile on your face will eventually penetrate into your soul, then this new cosmetic device may work miracles for that person in your life who is always unhappy. And how about those people who are happy on the inside but have faces that don't know how to smile properly and could benefit from a little smile training?

While this looks like a little dental torture device, the "Yumi," is a mechanical gadget that you insert into your mouth to "train" your facial muscles to smile (a nice, upward smile, not a downturned smile which may confuse people). According to Tokyo Mango (and I'll have to take their word for it, as I can't read the product maker's website), it comes in three colors and three strengths, normal for men, soft for women (why?), and rehabilitative for "seniors and children" (which would mean even softer?).

So what if the smile trainer makes you look like a monkey 4 times a day for 3 minutes? It's non-invasive and cheap - just $50 at this website. Those of us in the U.S. may have to wait until it comes to Amazon.
