I don't subscribe to the science because I've fallen for "science" so many times and I realise you can use it to prove or disprove anything. I don't like to imagine what "grok would have done" cos' it too speculative. Mark isn't my guru and I trust my own experience more.
What? - are you a blasphemous heretic that dares to think for yourself Yogabare??? Now, get prepared be burned at the stake!
