I'd like to encourage everyone to extend this line of thinking to even bigger adventures beyond the grocery store.

I couldn't be on my feet much last year on a tourist trip to Rome (city of cobblestones, no smooth sidewalks, lots of long stairs, city set up for lots of walking and standing). Once we looked into it we were amazed at how much we could do, pretty much everything we wanted, with a little pre planning. Most sites and museums had special access and elevators. There were inexpensive little golf cart sightseeing tours etc.

You'd be surprised how much you can do when you start to explore.

Also in daily life, you'd be surprised how much people are willing to help when asked. So many times I've had to confess to a shopkeeper that I can't stand anymore and people have instantly gone out of their way to bring me a chair or thought of solutions I would have never considered.
