Ghost in your genes
(Producer) New clues reveal that a second "epigenetic" chemical code sits on top of our regular DNA and controls how our genes are expressed, turning them on and off with consequences for our health. While we inherit the epigenome much as we do DNA, it appears to respond far more to our environment and lifestyles. So our stress levels and what we eat, drink, and breathe may leave an enduring imprint, not just on our bodies, but on the generations to come
