 Here's another thing too, Alec. You know how when you go to get your car serviced, they'll put that little sticker a lot of the times on the top corner of either your dashboard or your windshield. They'll put it up there and they'll say, when you reach this mileage point or you get to this date, you should just come and get your car checked for oil, things like that. How important is it that you kind of stick to one or two of those numbers that they give you?
