Specialization is for Insects

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.
