When you weigh yourself, the WiiFit tells you how many more pounds you need to lose or gain in order to make your goal. On a day when your weight goes up, even a little, it will tell you that you're going in the wrong direction. And if you do lose weight and it's not fast enough to meet your goal in time, it tells you.
This is annoying.
So Joy and I tell it our goal is to gain 20 pounds. Then any day when our weight goes up, it compliments us.
What they OUGHT to do is program it to occasionally say something different. For instance, "Hey, I know your weight hasn't gone down in a while and that can be discouraging, but don't sweat it. I mean, it's only a number. It's just one way to measure your health, and it has absolutely nothing to do with your value as a human being. I think you're great. Just saying."
