Author Marta Zaraska Talks About Her New Book and How Friendships Help You Live Longer

Author and journalist Marta Zaraska joins Lynn and John on Cool Science Radio today. Zaraska has written "Growing Young: How Friendship, Optimism and Kindness Can Help You Live to 100”. This book is based on hundreds of research papers and on interviews with dozens of leading scientists from fields as diverse as molecular biochemistry, cyber psychology, and zoology. Do you want to live longer? Miracle diets, miracle foods, miracle supplements may not be the answer. Friendships. Purpose in life. Empathy. Kindness. Science shows that these 'soft' health drivers are often more powerful than diet and exercise.
