At the moment, I am convinced that food supplements are the way to go to age gracefully. Our bodies profit immensely when we deliver important micro nutrients in sufficient levels- These might be higher than the recommended dose. When our metabolism does not suffer from lack, it can do its job a lot better and a lot longer. All the other fancy new substances still need a bit of testing. However, happy aging is a process concerning body and soul alike. I think, we can learn a lot of the inhabitants of the Blue Zones. Thank you for your interesting article, always a pleasure Gunnar.
