Alright, here is the really interesting take away from this clip- I have not seen anyone mention it yet, but I'm sure others caught it. At around 1:40 sec. the noble professor digresses for a moment to highlight the naturally inherent disposition of Japaneses people to resist catching Covid-19, due to a specific enzyme in their saliva. Uh... wut?

I have never heard anyone make mention of this saliva thing before, which is suspect and concerning in and of itself (my guess is the professor is 100% spot-on, otherwise he would never make mention of it during his big moment in the spotlight) now, add the likelihood for this enzyme to be in all or most Asiatic people, to include China.
