Wii Fit

Has anyone tried the new Wii Fit? I got one this weekend. The first step, after entering your height and birth date, is to get on the board and have your weight measured giving the Wii your BMI. After that, you take a "balance test". It somehow puts all these things together and gives you your "Mii Age". After plugging in my height, and standing on the board for the various measurements and tests, I got my results: I am underweight, 55 years old (my actual age is only 38), off balance and 'much weaker' than I should be. Ah yes. That's the way to start my morning off right! I wonder if the folks over at Wii know about my medal??
