hmm, maybe its some odd sort of Darwinism working itself out.
the hunters eat the meat, which they have to know on some subconscious
level is making them sick, but they just dont care.
then they breed (since the prions dont seem to affect fertility...
which is odd considering how many of them do their thinkin with their
pekkers..) ..and neglect more rugrats to carry on the self-destruction,
which would be indefinite due to hick breeding habits, but there is
the "law of diminishing returns" to consider.
sooner or later there will be more couch taters than capable backwards
i dare say that soon, they wont even be able to throw rocks with any
accuracy, much less use an Atlatl or boomerang.
then, we will see the rise of the "point-and-clik" internet "hunters"
who happily max out their plastic to buy "better aim" software.
let them eat prions.
