The guy is already showing symptoms of “Kuru” or the “Shaking Sickness” which has been shown to be a retro-virus that afflicts cannibals, usually acquired from eating infected brains.
I am not making this up.
That's (Kuru) in New Guinea.
I read about this years ago when a doctor went into 'the wild' with his anthropology wife and observed the natives eating the brains of the deceased elderly. It was done as a sign of respect and hope to claim the wisdom of the elders. His studies eventually determined that they were passing along a prion disease...like mad-cow disease.
