Couey: from my perspective, having somebodies blood sample gives you a huge bright signal about their medical data and their genetic data and their immunological state and very very very little information on their microbiome, especially what's on their skin or in their nose.
And so an extraordinary bait and switch is happening here where he's selling the same bamboozling lie about what we can do with a blood sample, and "what we would do with it", which is figure out all the bad guys in your body, instead of, what its most useful for, which is sampling you.
