Zen and the art of motorcycle maintenance, abridged, 26
Sometimes, the only way to acclimate yourself to engine noise is to take off the helmet and simply immerse yourself in it.
Of course, you might also try ear plugs—but that’s hardly very zen, is it? And to paraphrase the Kyoto school’s Masao Abe’s “One Bird with Two Wings” parable, “chicks with decent breasts almost never ride topless with guys who do the dorky earplug thing.”
—Which is something the truly enlightened student must certainly take into account before deciding on his course of action.
