"This is something that the vice president is very annoyed about and which needs to be resolved"
Too bad, now this makes me feel sympathetic with this toxic UK project.

I guess that explains the huge interpersonal variation on PFAS excretion in feces. Everyone's liver excretes a small amount of PFAS in bile, some people have gut bacteria that absorb it, other people reabsorb the PFAS from the intestine.
Not sure this will be a big change for PFAS decontamination, as the PFAS must first be excreted by liver, and it seems it is not a very efficient process.
what percentage of life do i get by ruining it? I like beef and alcohol so I need an answer.
You face a statistical problem. Even if we find convergent studies concluding your habits give you a X% increase of dying before age N, that will not tell you when you will die. You could be lucky and get in the (100-X)% side. Or you could be unluncky and get a cancer at age N-20. Or you could even die from an unrelated reason, like being hit by a truck.
The Kerr metric is 0 to 1. With 0=non-rotating to 1=c (c=299,792,458 m/s). The theoretical maximum is 0.998 c.
But rotation is measured in rad/s, c is m/s, so how does it fits?
Apologies for the mistaken identity, but why inject yourself into the conversation if you don't care about the point I was trying to make?
You said PTFE should be considered a PFAS, and I agree with you. But I do not want to loose my time on that point. The important point for me is the dangers of PTFE, whatever the classification we use for it.
As usual this kind of announcement should be readen while looking up crustal abundance of the required elements. molybdenum (Mo) and Tungsten (W) are note common, but not that scare. They are around the abundance level of uranium.
Chinese law requires Chinese companies to share data with the government upon request
I understand US government knows about the issue, as the US patriot act gives it the same power
You claimed that PTFE is not a PFAS
I did not, it was someone else. I am not interested into the semantic debate, the point for me is that PTFE can degrade into PFOA, which has a well-established a toxicity record (and is considered a PFAS by everyone).
With half-lives of 2.7-5.3 years for major PFAS compounds (PFOA, PFOS, PFHxS), it would take approximately:
5-7 half-lives (~15-35 years) to reach DuPont's 1991 internal guidelines 10+ half-lives (~30-50+ years) to reach undetectable levels
That assumes you could avoid new PFAS contamination while you slowly excrete them. Since they are everywhere, that does not happen. Cohort studies show PFOA (and PFOS and other friends) contamination just increases with age.
