Leave it to the Brits to come up with a holiday we’ve never heard of. It’s “National Kissing Day,” and it’s coming up on July 6. We got word of it via Interflora, their version of 1-800 Flowers, who are pushing the day hard in order to sell more flowers. Makes sense, but they went a tad heavy on the promotion: “Apart from being jolly good fun, kissing is good for us. Fact. For those with an athletic disposition it's worth remembering that an hour spent kissing burns off up to 600 calories, the same number as in six glasses of white wine or a medium bar of chocolate,” they said in a release. Who knew? And they add: “Kissing can help alleviate headaches, helps keep your teeth clean (Ed.: Really?) and gives us happy highs due to the oxytocin it causes our bodies to release.” Man, someone oughta market that holiday HERE!
