Longevity is having a moment far beyond Silicon Valley, and as we all look not just to live longer but to live better, In this episode of Next Question, Katie sits down with longevity researcher Dr. Rhonda Patrick.
What the science makes clear is that aging isn’t a simple cause-and-effect story. Genetics do matter, but they are only part of the picture and research shows it may be a smaller part then we think. How quickly your body declines — and what you do to combat disease and promote healthy cells along the way — plays a much bigger role.

The conversation covers why exercise is the closest thing we have to a longevity drug, why heart health impacts everything from mobility to brain function, and how supporting blood flow and oxygen delivery can make a meaningful difference as we age.
