I visited my parents tonight to reassure them I would be doing their shopping and delivering it.
They are both heading towards 80.
My mother has promised her last big shop to Sainsbury's was last Friday and that she would shut the gate and concentrate on her gardening.
In the next breath she told me she'd had a sleep that afternoon to get her energy up for her busy week ahead! She's still planning on going out and about to various busy meetings, but said it was alright as they bump elbows and don't kiss on the cheek anymore 
My father then told me that one of the members at his club was in hospital with suspected coronavirus. But he was taking extra precautions with hand washing so he would be alright to carry on going.
Aaaagggghh
They are just not going to self isolate, at all.
My parents in law, also heading towards 80 both said if it's their time then that's fine. Neither are stopping any activity at all.
I'm now worrying about an extra 4 people who won't help themselves and seem to be under the misapprehension that the NHS will be there if they get ill.
