Mark Greif’s Against Exercise is a hoot. “The haste to live one’s mortal life diminishes. The temptation toward perpetual preservation grows. We preserve the living corpse in an optimal state, not so we may do something with it, but for its own good feelings of eternal fitness, confidence, and safety. We hoard our capital to earn interest, and subsist each day on crusts of bread. But no one will inherit our good health after we’ve gone. The hours of life maintenance vanish with the person.”
