From the department of “did you know?” comes this interesting piece from Mary Roach in The New York Times:
The way you chew, for example, is as unique and consistent as the way you walk or fold your shirts. There are fast chewers and slow chewers, long chewers and short chewers, right-chewing people and left-chewing people. Some of us chew straight up and down, and others chew side-to-side, like cows. Your oral processing habits are a physiological fingerprint.
This was interesting too:
Round foods are particularly treacherous because they match the shape of the trachea. If a grape goes down the wrong way, it blocks the tube so completely that no breath can be drawn around it. Hot dogs, grapes and round candies take the top three slots in a list of killer foods published in the July 2008 issue of The International Journal of Pediatric Otorhinolaryngology (itself a calamitous mouthful). A candy called Lychee Mini Fruity Gels has killed enough times for the Food and Drug Administration to have banned its import.
