Next to male-female brain differences, an area of interest seems to revolve around the science of Epigenetics. You may want to read work by Bruce Lipton PhD, arguable the foremost authority today on research in that area. What is Epigenetics? It is the study of the molecular mechanisms by which environment controls activities of the genes and is one of the most active areas of scientific research. People sometimes say, “I’ve got the genes I’ve got and there is nothing I can do about it.” Oh yes there is. You are not a victim of your genes. In some sense you are master or mistress of your life. The science of Epigenetics has shown that you are able to create a life overflowing with peace, happiness, and love. Genes contribute about 30% to who you are. In their book YOU: The Owner’s Manual, Michael A. Roisen MD, and Mehmet C. Oz MD, pointed out that 70 percent of how long and how well you live is in your hands. It's high time to get busy managing the 70 percent—if you are not already doing that!
