I will look at that link later to refresh my memory, but I don’t trust anything that the CDC has to say on the subject, and I don’t trust studies that were conducted by the makers of things, nor studies that are conducted by organizations that have ties to the makers of stuff.
I have spent a great deal of time researching and looking at data. That has made me skeptical. Truth rarely comes out with respect to such things until 50 years down the road.
