Cellular biologist are beginning to disprove this idea, and form a whole new concept. Biologists now realize that the expression of our genes is controlled by their environment and our perception of the environment. Each one of us is directly responsible for our health and the choices the we make...the foods we consume, the emotions that we hold within, and our general attitude all contribute to the expression of our genes and their manifestations of health and disease.
Your health is not predetermined...you have more control than you may think.
