Genes are the building blocks of our lives. They control our metabolism and often form the basis for what diseases we could develop. You can influence whether risks are turned on or off by choosing an optimal lifestyle.
Epigenetics influence the enabling or disabling of our genes. For every person there is an optimum individual lifestyle and optimal environmental conditions.
Many age-related diseases are caused by a declining immune system. If we cannot deal well with inflammation genetically, this system needs support.
