Around July of this year, the number of people viewing my video fell. Recently I watched the video and discovered that YouTube is stuffing advertisements in front of it. I guess that is why fewer people are watching it. There does not seem to be a way to override this. The "monetization" option is not turned on. So, I downloaded it and put a copy at LENR-CANR.org in mp4 format. You can view it anytime, or download a copy:

The YouTube version is still here: https://www.youtube.com/watch?v=HjvL4zNLOGw The script in various languages is here: https://lenr-canr.org/wordpress/?page_id=1618
