I started doing that from last New Years Eve believe it or not.
Every day, I do some abs, crunches and a few exercises. I try to get 1 hour to go run or to go to the gym, but the phone keeps ringing.
I should learn to have sometime for myself, that will be my new years resolution.
I actually follow those, only because I'm a contrarian ;)
I can't tell you how helpful and valuable your post is for so many people that are hooked on laptop, I know how it feels.
That's the right idea.
