Intriguing and funny, Mental Floss the magazine bills itself as “Where knowledge junkies get their fix.” But the name made me wonder: Is there a way to have a floss that really is mental? How about whenever you pull out some floss, the container talks? (Like a a talking doll or action figure. We had a Teenage Mutant Ninja Turtle like that once.) Or perhaps as you flossed, the filaments could release a stimulant like caffeine, or a prescription drug that, absorbed through the gums, boosted your brainpower. The idea of running some string through your brain seems ridiculous to do. But it sure would nice to be able remove those little bits of trapped wrong information that rot neurons.
