Spirit Science, an animated series on YouTube that discusses some of the new-agey religious stuff, like how this is 3rd density and there was Atlantis and Lemuria, etc. Neat stuff. ANYWAYS, part of the series talks about how jews are an old sprit from some alien species long ago that inhabited the Earth and mingled with human spirit. This reminded me of this as perhaps, if even somewhat true, sprits inhabiting bodies they shouldn't ever have inhabited would cause all sorts of energetic deficiencies that would manifest in these sort of ways.
