I know what I'm doing if I live long enough to become too old and feeble to drive.
I'm hiring a highschool kid or two to haul me around in a sidecar rig in the afternoons, if I have to do any errands. I'll bet I could pay them peanuts, and still go wherever I want. Then I also still get the excitement of being out on the road.
Some are guard dogs of the flock. Some herders, search/rescue, or companions. We Devildogs are those, and also retrievers. Hell is our blazing dogpark, our frigid swimming hole. The fallen are our tennis balls. We don't leave the fallen behind, even if the master has to bring them home for us. Semper Fi, my friends.
