I was sent this link, it has the thoughts of a virologist, with a conclusion that outside exercise shaming people might not be the most effective thing to do. The argument looks coherent and reasonable.
Lucky you, for Christmas i got an off the shoulder dress woven with 7%metal fibres. It sparkles and looks fabulous, but it is cut to prevent anything being worn under it, it itches and it is totally cold. Still going to wear it and not complain.
