In a recent issue of Neuron and Science, new findings showed a link between epigenetics and retardation in mice and humans. As scientists search the cause of more and more illness and disorders, they find it is not faulty genes but faulty epigenetics. Our genes are fine but how we play them is different. Sometimes this difference can lead to illnesses, disorders and death. We also know that epigenetics is widely influenced by our environment. The environment is everything from diet, stress, weather, toxins, to how we think. Our bodies are influenced by the entire environment we put them in. These influences can cause epigenetic changes to try to deal with the changing environment. Sometimes this works and sometimes it leads to problems that can make us sick.
