I suppose each person in the household could walk the dog as their exercise?
That's what we will be doing I think.
Likewise, combining each person's exercise with dog walking which although Boris didn't mention it is just as essential as going t- dog walking.
We can live within both the letter of and the spirit of all this except this "going shopping as infrequently as possible"
I've avoided panic buying so far, and I've been lucky enough to be able to buy enough loo roll and rice to be going on with.... but it now seems to be necessary to make daily (or more frequent) trips to all the various local supermarkets in a forlorn hunt for some basic things we are now running short of:
flour, yeast, pasta, ibuprofen/paracetamol, dog biscuits, all of which have disappeared from the shelves.
Individually, none of these are "essential"... l could make (rather coarse) pasta, or even live without it for a couple of weeks, and if it came to it, I could probably dream up a recipe for dog biscuits, but neither are possible without flour. Meanwhile supermarket shelves are filled with a million kinds of processed foods, easter eggs, plenty of meat (which we don't eat), 20 different brands of yoghurt... i can even still buy some rather nice soft french cheeses from unpasteurised milk - which have long been almost unobtainable in their country of origin!
Sorry Boris - but right now "infrequently as possible" = "more frequently than usual" for many of us.
