Why do people...

...leave their cars running while they sit in them? while they wait in line for their take-out order? in the parking lot while they go into the corner store for a pack of cigarettes? Is it really just too tedious to turn off the car and start it up again?

...buy an expensive power mower to mow their patch of lawn so they don't have to work so hard, and buy an expensive membership at the gym so they can work out?

...work 80-hour weeks so they can purchase boats, summer homes, exotic vacations and other leisure aids?
