For his new book, Healthy to 100, longevity researcher Ken Stern wanted to answer a question that nagged him: Why do so many people in some European and Asian countries live long, healthy lives? How can Americans be like them?
For six months in 2024, he traveled to five of the most successful aging nations — Italy, Japan, Singapore, South Korea, and Spain — to find out why their average life expectancies were often six years longer than ours and to interview residents in their 70s, 80s, 90s and 100s.
