I live in Southwark, and it's always astonishing how people don't wears masks around here. Customers, Cashiers, Barbers... Iceland, Off-license, Asda... It's like people don't care at all. Only about 50% of people are wearing masks. Sharp contrast with France where people need to wear masks all the time, and it's heavily enforced. I don't expect the number of cases to go down TBH.
That masks are scientifically shown to do anything. They are more superstition at this point. You can look at numbers between regions with high mask usage and low mask usage and there's literally no correlation. Meanwhile they are contributing massive amounts of plastic waste, textile waste, and provide a placebo while also providing alienation between individuals. The larger factor that correlates is population dens…
There are probably issues with how much people obsess over them though. I feel like people get a false sense of protection. People tend to stand right next to you in line when masks are required rather than keeping some distance!
