My Mii character was a cute little thing until I put in my weight and he blew up like a beach ball. I don't look like that! Well - bald, bearded, and glasses but that's about it. :) Then after spending way too much time figuring out what I'm supposed to be doing on that first test, it showed my Wii age as..."46, that's your actual age. You're in good shape!" Then why do you have me look like a beach ball? hahaha
So I took the test again since I knew how to do the test this time and they gave me a different test :( I gained .3 pounds - say what? I didn't eat or drink anything in the last 3 minutes from the last test! - and a new Wii age of 51.
