I'm still wondering how one of my neighbors (no, Pete, it's not you) can spend 44 minutes (I clocked it precisely with my watch this time) mowing his back yard with a loud gas-powered lawn mower, given that his back yard is only about 50 feet by 40 feet. This particular fellow, who seems to be in good health, is not the only guy who zones-out while pushing a noisy lawn mower. I've seen others do it--the loud noise seems to put some people into Zen-like trance. It's the same look I notice in other folks who get to that same mental state by simply walking down a street or through a park. I'm wondering how my neighbor would react if I offered him a chance to exchange his noisy mower for a cheap green mower like the one I've owned for ten years - - it has no engine, so it's fume-less; it's also human powered. I suspect that he'd miss the roar.
