a human being should be able to
change a diaper.
plan an invasion.
butcher a hog.
steer 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.
