Wednesday, December 30, 2020 

This Wednesday, December 30, is the last day on which a person born in the second millennium can get a Wii Fit Age of 19 or lower in the game Wii Fit, assuming that the person’s actual date of birth (DOB) is used on his or her Wii Fit profile. If a person, let’s call him “Joe”, was born on 12/31/2000, the last day of the second millennium, then tomorrow will be Joe’s tenth birthday. If Joe takes a “Body Test” and performs superbly on it, Joe will get a Wii Fit Age of 19 because, for the rest of today, that is his current age. Starting tomorrow, he can no longer get nineteens; a superb performance will instead get him a “20” because he will be twenty years old.

In Wii Fit, the rule for Wii Fit Age is that the lower the Wii Fit Age, the better the person’s health. For children, the lowest possible Wii Fit Age is their current age. For example, if a 5-year-old child takes the Wii Fit Age, the lowest Wii Fit Age is 5. For a 12-year-old, that minimum is 12 instead. This rule holds up to age 20, after which the minimum is set at 20. A poor performance will result in a higher Wii Fit Age. Since the “minimum” Wii Fit Age does not go past twenty, this means that users who are old enough to purchase alcohol (≥ 21 years) can get a Wii Fit Age that is lower than their actual age; for example, a 25-year-old can “beat” his or her age by 5 years since 25 − 5 = 20. And if you’re 28, you can “beat” your age by 8 years.

Once you turn 20, you will never again get a Wii Fit Age of 19 or lower, even if you complete the test perfectly, unless you use a “guest user” or an alternative profile with a different DOB, or unless you change the DOB on your profile to a newer date.

If you are 20 or older, and your Wii Fit Age matches your current age, the Wii Balance Board tells you that you are in good shape. If you are 19 or younger, and your Wii Fit Age matches your current age, the Wii Balance Board says, “You’re still very young!”
