As always, thank you for reading and for sharing my posts. I will likely update this post soon with more information, however in the meantime please check out the following links if you have questions:

1. The testing methodology for all tests reported on on this blog.
2. A video showing you how to search the blog most efficiently, given there are over 2,700 posts and pages here.
3. My documentary feature film on childhood Lead poisoning.

Please let me know if you have any questions. With 1.165 Million unique readers in 2020 alone I am not always able to answer each and every question personally, but I do try.
