We are bombarded with advice and information about diet and exercise, but what about the impact of friendship, optimism and kindness on our longterm wellbeing? It is eye-opening to discover that a strong support network of family and friends lowers mortality risk by about 45 percent, while volunteering your free time reduces the chances of early death by a staggering 20-60 percent, depending on the study. Science journalist Marta Zaraska is the author of Growing Young: How Friendship, Optimism and Kindness Can Help You Live to 100. In this episode of the LLAMA podcast, she discusses the peer-reviewed studies that suggest living to a great age is about more than what we eat or how much we move. We cover how caring for children motivates us to keep on living and why Marta's long-held beliefs about aging and longevity were shattered through an understanding of the research.
