Got some really nice info to share with the rest of you guys, that are into science. If you've never sat down to think, just how much "power" am I using to do this thing I'm doing right now compared to something else in the world? Like, how much raw physical power am I using when I am typing on this keyboard vs to someone pitching a baseball. If you've never thought of it the slightest.. here's a list to get you started on thinking.

What's a joule?
Picture the energy to hold a kiwi in your hand, and move it 1 meter (3 feet) straight up in the air. That's 1 joule.
The following are in millions/ billions of joules for the ones higher up the list. This is a scale of from 0-68, how where they rank in terms of power exertion.
