I think Wii Fit most certainly help keep people in shape. I occasionally use Wii Sports as exercise and it wears me out. To have a software that is designed specifically for fitness I am sure will work even better.
I also use Brain Age in hopes it wards off Alzheimers. If nothing else, I can definitely tell my memory, concentration and attention to detail has improved. 40 years or so years from now, if it adds a year or two (or even a day) of lucidness to my life, I will feel it is worth it. Besides, it is fun and I am now a Sudoku addict.
