Epigenetics teaches that we, indeed, are not doomed by our genes and that a change in human consciousness can produce physical changes, both in structure and function, in the human body. We can modify our genetic destiny by turning on the genes we want and turning off the ones we don’t want through working with the various factors in the environment that program our genes. Some of those signals come from within the body, such as feelings and thoughts, while others come from the body’s response to the external environment, such as pollution or sunlight.
