So ... (har-de-har-har :P) ... in what foods (other than younglings) can this protein be found? And does it have to be intra-venously administered or can it be ingested?
Furthermore, all joking aside, it is funny how often old myths turn out to be ... not correct, not 'containing a kernel of truth' ... maybe apropos is the word I'm looking for? Vampires immediately spring to mind and many creation myths correlate to the big bang; the many flood myths ... there are many more things like this.
I guess it is merely a function of the shotgun approach which favours Nostradamus and is inherent in Shakespeare's monkeys: spout enough vaguearies and every so often an old wives tale will have correlation to reality.
