Whenever I go to the gym, I think about the waste of energy. For most of history, there were no such things as gyms because people expended energy by walking, farming, doing household chores, climbing stairs. Now, it’s kind of funny thinking about all the people at the gym cycling on the spot, going nowhere. Or running a treadmill, going nowhere. Or climbing on the StairMaster, going nowhere. Or lifting weights, up and down, up and down, then putting them back exactly where they were before.
Sometimes, I think that all those machines should be hooked up to generators so that the dissipating energy could be put back into the electricity grid. Wouldn’t it be great if the roomful of people could power a laundromat? We could arrive at the gym, load up the washing machine and ride our way to clean clothes.
