Quick takeaways
Eli Metchnikoff believed in the potential of science to cure aging and extend life through his research on the immune system and the role of the intestines.
Metchnikoff's theory that consuming yogurt could combat aging became a global trend, but his research did not lead to the promised anti-aging cure, highlighting the complexity of aging.
Deep dives
The Quest for Immortality
Famous scientist Eli Metchnikoff believed that science could cure aging and extend life up to 150 years. He researched the immune system, which won him a Nobel Prize, and later focused on aging. Metchnikoff believed that aging was a disease and that the root cause was in the intestines. He popularized the idea of consuming yogurt to prevent aging and extend life. However, his optimism was challenged by the outbreak of World War I, and he died at the age of 71, still searching for the secrets to a longer life.
Chasing the Death Instinct
Metchnikoff became interested in aging after facing personal losses. He believed that a "death instinct" should develop in people after living a long and healthy life, leading to a painless old age. Metchnikoff researched aging at the Pasteur Institute in Paris, conducting experiments on animals and exploring the role of the intestines. He became obsessed with the idea of finding the death instinct and interviewed elderly people at the Salpêtrière hospital. However, even in poor health, they expressed a strong desire to live longer.
Yogurt Mania and Disappointment
Metchnikoff's theory that the consumption of yogurt could combat aging sparked a global trend. Newspapers touted yogurt as a cure for aging and a secret to a long life. The yogurt industry boomed and people considered it a safe and affordable option. However, the hype and commercialization overshadowed Metchnikoff's caveats and the complexity of aging. In the end, his research did not lead to the promised anti-aging cure, disappointing many who had believed in his theories.
Legacy and Continued Pursuit
Metchnikoff's belief in science's ability to prolong life and combat aging continues to inspire today. Scientists and researchers, like J.O. Shansky, explore ways to extend human life and improve health in old age. While Metchnikoff was unable to find the secret to immortality, the quest to understand and potentially manipulate aging and lifespan continues. The desire to live longer and maintain a good quality of life while aging remains a foundational question in science and a driving force in research.
In 1899, Elie Metchnikoff woke up in Paris to learn that he had defeated old age. At least, that's what the newspaper headlines said. Before long he was inundated with mail from people begging him to help them live forever. The only problem? He didn't know how to do it.
At the time, Metchnikoff was one of the world's most famous scientists. And he believed aging was a disease he could cure. He dedicated his life to that quest, spending his days interviewing centenarians, pulling gray hair out of colleagues and old dogs, and boiling strawberries — all in the pursuit of eternal youth. If you've ever had yogurt for breakfast, you likely have Metchnikoff to thank.
