It's actually a little more than that. You see I'm 19 have quite a bit of responsiblity, work, college (even through the summer), getting married.
I don't have

of time to watch TV (assumption 1)
When I get the time I will watch recorded BSG and that is the only thing on TV I ever get to watch.
Me and Melissa love to go out and walk (when I have time), we both aren't overweight and exercise for health.
This is a great way to spend some time (together, even with my family, which are at the age where you don't see enough of them) while getting a little enthused about getting healthier. (which this software does)
I'm a family kind of guy and anything to bring a family that is falling apart, for whatever reason, together is a huge accomplishment. (Wii fit or just the Wii is great to have fun when life gets too busy to be a harcore gamer.)
The truth is, becoming a casual gamer kinda lets me see more of the world for myself other than just behind the computer screen.
