You are welcome. I used to post more of these vids (because I watch them) but mostly, it seems, either people ignore it or haven't the time to comment. A small minority do.

Also, there is a sort of etiquette that if someone posts something on a subject, one would expect this would be read before someone posts on the same subject anew. Namely novichok. I am in DADE mode so I shan't be drawn : ). I think you have already commented on this.
