The Indolence Quotient
Take the percentage of your life you spend unconscious while the sun’s up, subtract from it the percentage you’re gainfully employed while the sun’s down. Multiply by 100, and add 100.
You will then have a number, resembling an IQ, which describes one’s rate of indolence, relative to average folk who hover near 100. The higher the number, the more of a bum. The subtraction step ensures folk who work after dark don’t get penalized, and a number below 100 implies workaholic.
