Obviously the doctors at local level are giving different advice on the ground to that being given by the government.
My mum in Cornwall (well but elderly, a bit asthmatic, had a heart operation) phoned her doctor after the 'ease of the lock down' announcement.
'Can I go out?'
'Have you had an asthma attack in the last year?"
"No."
"Do you drive?"
"Yes."
"Then you can go out in your car for a drive. Keep the windows up and don't get out, just drive about and then go straight home. On no account get out, especially at a supermarket or garden centre."
Since the places she quite fancied going were the supermarket and the garden centre, that should keep her in for a couple of weeks. Thank you doctor!
