Topics

Longevity and Science

Thinking about living well for longer can raise questions that feel both personal and scientific. These conversations explore what longevity means beyond a number, from everyday movement and social connection to sleep research and measurements of organ aging. David Stewart considers how fitness, resilience, and accessible habits fit into a fuller human experience. Dr. Nicole Moyen discusses temperature regulation, menopause, and the questions researchers are asking about sleep quality. Paul Coletta introduces proteomics and explores how biological measurements might guide action and track responses. Along the way, the discussions ask what health data can tell us, what remains uncertain, and how to distinguish useful information from the appeal of optimization. There is room here for curiosity about everyday life too.

Do researchers know exactly why people wake around 2:30 or 3 a.m.?

“The short answer is I don't think we have a clear understanding of exactly what causes that wake up. Um there's not one single answer, I should say.”

What does Paul Coletta mean by a closed loop health system?

“Bridging health insights or health data to targeted action. It needs to be actionable. And then here's the big part measuring the response, a validated health outcome. That's the closed loop system.”
