From the youtube aether put up...it was talking about how even before mri machines, this guy de la marr, I think, did an experiment with his wife who was an rv'er. She only needed a drop of blood from a cow(that was sick and the owners couldn't figure out what was wrong) and somehow they wound up with an image of cow and in its stomach was a rod or something and that is why the cow was sick. So in a drop of blood contains the whole memory/image of the cow...like a whole copy. If I;m making sense!lol
