As an 'At Risk' person of 72, I am doing everything advised.
I get my daily excercise by walking the 400 mts to the corner shop on our estate. The owners ensure there is no crowding and people keep there distance which customers respect.
I'm pretty sure that if this goes on for weeks I'll become stir-crazy.
People who openly and deliberately flout the advice about congregating are nothing short of selfish unthinking criminals and should be treated as such. Maybe under rapidly produced legislation, they will be !!
