A human being should be able to change a diaper, plan an invasion, butcher a hog, design a building, conn a ship, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve an equation, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly…specialization is for insects. – Robert A. Heinlein
