Love it!
I can think of more ideas: hanging laundry out on the clothesline, mixing cookie dough by hand, kneading pizza dough, making homemade ice cream with a crank machine, shoveling snow rather than using a snowblower, raking leaves, splitting wood for the woodstove, participating in live theater/musicals vs. just watching movies (and making music vs listening to iPod, too).
Oh, and volunteer physical labor vs money - I always get quite a workout at the library's semiannual book sales hauling boxes of books up from basement storage, moving and setting up tables, returning extras back to storage for next time, cleaning up.
