Your Thoughts Control Your DNA: Biologist
The common idea that DNA determines so much of who we are—not only our eye or hair color, for example, but also our addictions, disorders, or susceptibility to cancer—is a misconception, said stem-cell biologist Bruce Lipton, Ph.D.
"You find yourself to be more or less a victim of your heredity," Lipton said in the documentary "Biology of Belief." "The problem with that belief system is that it extends to another level. … You become irresponsible. [You say,] 'I can't do anything about it, so why try?'"
This concept "says you are less powerful than your genes," Lipton explained.
He said a person's perception, not genetic programming, is what spurs all action in the body: "It's actually our beliefs that select our genes, that select our behavior."
