Although I had never done it on my own, changing the oil in my car has always seemed like the car-oriented task that anybody could figure out how to do themselves. I thought it ranked slightly higher than adding gasoline on the difficulty scale. This is a bold statement from somebody that has little to no natural mechanical proficiency. That has never changed his own oil.
Thousands of years ago, sleeping outside was a way of life, not an option. As the human race has become domesticated, we have moved back outside for entertainment. Perhaps people wouldn’t feel the draw of sleeping under the stars if it wasn’t for our ancestors. Camping didn’t become popular until the early 20th century. This is, perhaps, because of the rising affluence of Americans, or because of the institutionalization of the national parks and recreation programs. These days, camping is usually associated with Boy Scouts, retirees, the homeless and people at music festivals. Not people that you would normally lump together.
