In Japan now who's government runs their healthcare, once a year employees of every company must be subjected to a waistline test, among other things, to determine fitness. The goal is 33.5 inches for men and 35.4 inches for women. If you don't meet the goals then you get to lay on some shrinks couch a few times a week and the company must pay higher premiums for your healthcare...and that can't be good for your job. This is similar to the United States' Safeway Amendment which says that the health, fit people can pay lower premiums.
Japan is already the thinest industrialized nation in the world, that seems good enough to me. Oh, and what's going to happen to sumo wrestling?! If sumo wrestling dies then we're all in trouble!
