It came up at a work thing recently, where we were asked to bring in our bicycles for an event, and I was the only one who doesn't have one.
We live on top of a hill, so there's nowhere I'd easily be able to cycle to (or rather, I could whizz down the hill but getting home again would be a bugger). But even when we lived in a village down in the valley, I would either walk to local places or drive to ones further away. And I've never been one for cycling for pleasure - it's just not something I'd ever do. Had a bike as a kid and then at some point in my teens outgrew it and that was that.
DH i s super fit and goes mountain biking, but that's different - he'll often drive to get to good biking trails, but he'd never just cycle around on roads.
Is that unusual? Do most adults really have (and use) bicycles?
