In this NOVA science video, researchers discuss epigenetics. Imagine genes are like computer hardware. Epigenetics is like the software, that tells the computer when to work, when to rest, what to do.
Your heart, skin, hair all have the same genes. Epigenetics changes the genes into the type of cell you need in a certain part of your body. AND, they are influenced by the life you lead.
