Longevity expert Ken Stern joins Punk Rock HR to talk about what helps people live longer, healthier lives and why relationships play such an important role.
Ken is the author of Healthy to 100, a Wall Street Journal Best Book of the Year, and chair of The Longevity Project. His research explores how social connection, public policy, and community structures influence longevity. In this conversation, he shares lessons from countries like Japan, Singapore, Italy, Spain, and South Korea, where people routinely live longer than Americans.
One of the most striking insights from Ken’s research is the impact of loneliness. As he explains in the conversation, “loneliness, on the downside, [is] equivalent to smoking 15 cigarettes a day.” Social isolation creates real physical and emotional consequences. The strength of our relationships, the communities we live in, and the policies that shape those environments all influence how long and how well we live.
Ken also challenges long-held assumptions about the structure of life itself. The stages we take for granted, including school, work, and retirement, were invented relatively recently. Countries facing rapidly aging populations are already redesigning those structures, especially when it comes to work. In Japan, for example, many older adults continue working in flexible, part-time roles that provide both purpose and social connection.
The conversation raises a bigger question. If life expectancy has doubled in the past century, why are we still organizing our lives the same way? For HR leaders, policymakers, and anyone thinking about the future of work, Ken’s perspective offers a reminder that longevity is shaped by social, cultural, and political forces.
If you’re thinking about what the second half of life could look like for yourself, your workforce, or society, this episode offers insight and a grounded look at how we might build healthier, longer lives.
