The Fountain of Youth

I am 58 years old. In fact, next month I'll be 59. In other words, I'm getting up there.
While we were in Utah visiting our youngest daughter and her family, we were introduced to the Nintendo Wii - in particular the Wii Fit. All of us had great fun creating our "Miis" and playing some of the fitness games.
Part of the program is an assessment of what shape you're in (including BMI and weight), and then it tells you your 'Wii fit age'. Mine was 53, which I thought was pretty good. Actually I'm very impressed with the program. It keeps track of how much you 'work out' with it, and as you progress it unlocks new games (or higher levels of current games) to keep your interest going.
After we got home I decided to use some of our Income Tax refund to get our own Wii. I have always had trouble motivating myself to exercise, and everyone in our family could stand to lose a little weight.
Sunday night we got our new Wii hooked up. We didn't want to actually play any games (it being the Sabbath), but we did do the body test. Bill (who is 62) has a Wii fit age of 63. Tim (who is 12) was 15, and I was right on target at 58.
Monday, while Tim was at school, I put in half an hour on the Wii. I had the top score in every game I played (the advantage of being first!). I did the body test again when I was done, and my Wii age had dropped to 43. Overnight I had lost 15 years!
Naturally when Tim got home he broke most of my records (but not all of them!) He was pretty cocky about how well he had done on the ski jump, but he couldn't match me in deep breathing. I also still hold the record for tightrope walking.
Today I put in another half hour. I set records in some games Tim hasn't played yet (like the Hula Hoops), found some games that my records are hopelessly behind his, other games where I am barely behind him, and a couple where I regained the lead - most notably the ski jump!
When I did my Body test, my Wii fit age had dropped to 33!! That's 25 years in two days. Do you think I can get down to 0?
