Taking care of the body has always been a common obsession. Even when we are not starving or thirsty or naked, we still give an inordinate amount of attention to our bodies. We pamper the body, decorate it, exercise it, protect it from disease and pain, build it up, slender it down, drape it with jewelry, keep it warm or keep it cool, train it to work and to play, help it get to sleep, and a hundred other things to serve and satisfy our bodies.
