The way I look at it is that it is just another measure which may help to reduce transmission and so protect vulnerable people. Every little helps in my view. Keep your distance, wash your hands, wear masks indoors, take vitamin D and keep yourself as healthy as possible (ie not overweight), take the vacccines. All these things should reduce your chances of being killed by Covid (or infecting someone else). It is a pain in the arse for all of us but surely there are not many other options at present. Has anyone got any better ideas?
