You don't have to be raised on a farm to learn this. I was born and raised in a very large city and learned a lot of this stuff by having to work around the house to earn my allowance (mowing the lawn, painting the house, changing the oil in lawnmower & cars, helping build a new deck, etc etc). I also learned basic construction skills, metal working and welding in gasp my undergraduate art classes. This came in very handy when I had to build the walls, kitchen and bathroom in my Brooklyn loft many years later.
