Update: I am currently typing from (roughly) a praying position, as even the kneeling-chair that work has bought for me hurts rather than helps my back. The one I have at home, though, is so comfortable that I intend to attach a flashing yellow light to it and pretend that it’s a Shopmobility buggy.
Anyone with a driving licence will, of course, already know from the copy of the Highway Code they keep in their glove compartment that those motorized old people are permitted to travel (at eight miles per hour maximum) down a dual carriageway? I mean, I don’t want to pick on vulnerable road users—solidarity of the oppressed and all that—but… but…. Who would really, genuinely ever want to do that? Ever?
