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

Specialization is for insects_{:Robert A. Heinlein}.
