I didn't think you'd meant anything by it, no worries (just some people make much of the oddest things.)

Look - not up for duelling work myself right now, but if you want space or someone to supervise (if I can wrangle the time) I'm glad to. And as I said, the stairs are yours if you want them. (Not the most exciting option, but effective enough.) As for a walk - well, I did it Tuesday at a stiff pace, about two thirds my usual time, and it helped.

I miss the hills near where I grew up, really. Lovely balance of exertion and nice views.
