I see people as driving around in little cars known as "bodies." When the car is new, they get around, can wave through the window or roll it down and say hello. When one hits a bad bump, or gets into a fender bender, or the car gets rusty, you can't get around anymore, maybe you can't roll the windows down and chat, or the windows fog up and you can't really see each other clearly. But the driver is still in there. Until the car just won't start-up anymore.
