There was a time in rural America when families had no choice but to have gardens, hunt, work with wood, can/preserve food, make and/or mend their own garments, know about and be able to administer home remedies for ailments and anything else involved in staying alive. Kids were born at home and the dead laid out (waked) on the dining room table so family and friends could pay their last respects before they buried them out back.
Every family member eventually knew how to do just about anything that needed to be done. They were almost self-sufficient.
Technology has slowly changed things.
