A human being should be able to …

change a nappy
butcher a pig
conn a ship
design a building
write a sonnet
balance accounts
set a bone
comfort the dying
build a wall
take orders
give orders
act alone
cooperate
solve equations
analyse a new problem
pitch manure
cook a tasty meal
program a computer
fight efficiently, and
die gallantly!

— Robert A. Heinlein
