Absolutely, Chi Kung practitioners have been doing this for centuries, as have Buddhist monks, and meditation yoga practitioners.  They just haven't said so.   Nothing new here at all.  Of course, in the modern era, unless science can can make its own confirmation, nothing is true.  Sad, but true for science.  Now, I have an astrologer acquaintance who has some interesting things to say about August, the 8th month, the 8th day, 8:08 PM People's Republic of China Time, but since it's not about DNA, it will be off topic (on the other hand, actually, it is quite possible the DNA of Hu Jintao might undergo some surprising changes on that day, or maybe a little before, or after...but maybe I shouldn't be too hasty here in hinting something very specific will take place...because that is not true...rather, that my acquaintance knows only that Hu Jintao will be subject to some very powerful 'cosmic' energies that cannot be avoided by him...we hope he will make some good decisions, which themselves might change his DNA for the better, as well as conditions for the Tibetans).
