Here are my thoughts.

A young man/woman should know the following:

Be able to change the oil in a car.

Be able to change a tire on a car.

Know fire arm safety.

How to handle a knife.

How to sharpen a knife.

Know to stand up when a lady enters a room (for the men)

Know to stand up to shake someones hand.

Know to look someone in the eye when shaking a hand.

Know how to shake hands. Not limp, too firm, grasping only the fingers etc.

Know how to start a fire and keep it maintained.

Know how to balance a checkbook. (goes with basic math I guess)

Know how to save some money for a rainy day.

Know basic manners (please, thank you, etc.)
