Surely the important point to all this is to avoid close contact with other people. Like others here, I live in the back of beyond and walk our dogs every morning. I seldom see a soul and those that I do glimpse are inevitably some distance away, so just a cheery wave. I really cannot see why folk should not go digging, walking the dog, or indulge in other solitary pursuits. It's important for us old fogies to keep fit and active, and as long as we understand how the virus is transmitted, what the symptoms are etc. then we're intelligent enough to keep ourselves and others safe.
A good point from Badland regarding the parlous state of the NHS, made a damn sight worse by the loss of so many nurses, foreign nationals, as a direct result of Brexit.
