Sorry for the third degree, grannyknot (You held up under it very well!)
But there are many places, most of them outside London, where the buses only run once a day into the nearest town, and passengers have to walk a long way from their home to the nearest bus-stop, using a stick to help them. even the shopping trolley is hard to manoeuvre with only one hand. Many others live in towns, but have difficulty getting to and from the bus stop, or on and off the bus, and even in a big city like Edinburgh, they may have to get three buses to go what is a shortish district as the crow flies - One to avoid a steep hill, one into the town centre, one out again to their destination. The Age Scotland link has some interviews with such people.
