Many of the guys in high school with me (class of '83) worked on their cars. Certainly the basics like an oil change. Now you're knowledgeable in high school if you know how to change a tire. Of course tires and engines are much better now. Most people mowed their own lawns back when I was young. I mowed a few yards for others, and some just when they were on vacation, but most people did their own or had one of their sons do it. A few people would pay a neighbor kid like me to do it. Now lots of people pay a company to take care of their lawn. Of course, I live in a much more expensive neighborhood now, so maybe someone in a more suburban/rural area still doesn't see as much hiring for lawn care. I still mow our yard, but partly for exercise and partly for the sense of accomplishment; i.e. "it's done".
