„The duration of the life of men may be considerably increased. It would be true progress to go back to the simple dishes of our ancestors. … Progress would consist in simplifying many sides of the lives of civilised people.“
— Élie Metchnikoff Russian-French immunologist, embriologist, biologist, Nobel laureat 1845 - 1916
