A thought provoking video. I would not however dismiss practices such as astrology, numerology etc and phenomena such as crop circles and paranormal abilities as bunk as some commentators have done; In the first place have not done the research. Secondly, I am aware that some research claims to validate such phenomena. Finally it is entirely reasonable to propose hypotheses for phenomena while recognising that these hypotheses may be wrong. Acupuncture, once considered pseudoscience is now generally accepted as an effective complementary medical treatment.
