What with TV, video games, and the Internet demanding so much attention, it's hard to get today's kids off their duffs and outside for some exercise. That's not saying anything you parents out there don't already know. But here's something you might not know: there is a definite solution to this problem. All you need to do is install an industrial-sized aquatic tank (preferably outdoors, most likely in the backyard unless your neighborhood association's bylaws are particularly flexible), make its environment suitable for habitation by otters (plants, branches, rock formations; consult your local library), and then put some otters in there. Why would anyone want to play "L.A. Noire" when they can play with an otter?
