I only skimmed the subject article last night. Tonight, while waiting for Jimmy Fallon, I read the Wiki article on prions (quickly scanned it, actually). Perhaps there is apparently, at least a bit of concern regarding the use of urine that may contain prions if it comes from animals that are not proven to be healthy. It may be a very long time before the issue of prions causing disease is understood. If you want some guaranteed anti-insomnia reading material, the link is:
http://en.wikipedia.org/wiki/PrionJust curious, does anybody know if CWD was a problem prior to the widespread use of deer urine. Memory tells me that it was first described somewhere in the mid-west.
Fallon's on - gotta go!
