I posted a link in the Covid thread about a scientist proving that viruses in general and Covid in particular are spread by both aerosol droplets of less that 5 microns and much larger droplets of up to 100 microns. The article demonstrated that the virus moved by air much more than they originally thought and because of that I shall continue to wear a mask in enclosed public spaces as much as I can. It is personal choice. I used to think it was just to stop me spreading it. I am now more of the opinion that masks can also be effective in preventing me catching it!

This is round about the best article I have seen on the effectiveness of masks and it is criminally negligent of the government to not make such points clear and available to the general public.
