Making it mandatory to wear 3 layer masks outside would cut infections by a large margin. Other countries were doing it months ago we only really started a week a go! Older people are not stupid in general they do things to limit risks, like not going to raves, washing hands several times a day.
A lot of deaths have been in care homes or connected in some way to care homes, when the older person is typically over 80 and their safety is more dependent on others. Although I admit many people over 50 have been hospitalised like Boris.
What's happened to track and trace, if new infections are around 700 a day and were have 5,000? government paid tracers, surely we must be murdering the virus. If people are not co-operating in a reasonable way I would make it a criminal offence as they are seriously endangering the lives of other thousands of other people, like drink drivers.
