Brain Controlled Tail
I don't know how to start this.
You know how sometimes you wish you had a tail? Not a (possibly) useful monkey tail, but one a bit like a dog, to wag and stuff? No, me neither, but evidently someone thinks people do.
Soon, you'll be able to buy and wear a tail that is controlled by your brain, reflecting your mood. Just like a dog. Only in Japan (as far as I can tell, it's for real).
