Dietrich Klinghardt is not necessarily the most credible source of information.
See, e.g., http://scienceblogs.com/insolence/2010/03/26/your-friday-dos... for some critical commentary (from a source consistently critical of all That Sort Of Thing; read with appropriate caution if your general opinion of "energy medicine", "integrative medicine", kinesiology, homeopathy, etc., is more positive).
So, when Klinghardt established this extremely pronounced correlation, where did he publish the results and by whom have they been checked?
