The trouble with guys who still go on and on about low percentages (and continue patently to not understand how viruses spread but are instead trapped inside the land of average) is that in practice it is used an excuse for their Trumpist behaviour of not wearing a mask at the slightest opportunity. They consider themselves entitled to breathe over everybody else. The only question for the rest of us is whether the less bright less educated refusenik crowd parroting practical nonsense can be side-stepped in the UK or not. One London friend thought probably best to stay away at least during the coming winter months when people spend less time outside , so we are talking at least not until April 2021.
