A Moment of Science
Ever wonder why it's so hard to carry open beverages without spilling anything?
These days, lots of people get their exercise at gyms and health clubs, oftentimes by walking or running on treadmills–that is to say, running without going anywhere. If you’ve ever been on a treadmill for some time and then suddenly stepped off it, you’ve probably experienced the weird sensation that you are suddenly moving much faster than you think you should be.
But unless you have a body like a kangaroo, the amount of energy needed to hop regularly when your mass is above a certain amount will be more than you can afford. Try hopping to work tomorrow instead of walking and see how long you can manage it.
