Gaming blog Joystiq looks at the health and fitness mode of Wii. Like BrainAge for the Nintendo DS, the Wii's fitness mode runs you through a series of tests (in this case physical, using the Wii's motion sensitive baton-like controller), gauges the results and then awards you a "fitness age" based on your scores. Seems like a pretty cool use of the Wii platform, and all the more reason for me to get one come springtime.
