I share some of your doubts on the efficacy of masks, Steve, but I also don't think they do me any harm providing I refresh them frequently, which I do. So I will keep on wearing them where they are advised as long as that is the official position. At the same time, I had a meal in a pub last weekend and sat unmasked for a couple of hours. I even went to the bar more than once when I saw it was quiet. I didn't lose any sleep about having put myself in danger as it was quiet enough to maintain social distancing.

When we were first required to wear masks in shops, I used to snatch the mask off as soon as one foot had passed through the exit. It wasn't long before I found myself half way up the car park before I remembered that I still had the mask on. Now, I can't be bothered to take my hands off the trolley before I get back to the car.

As far as people not seeing my face, with my looks, I could be doing the world a service.
