@the.living.room.pod: We talk a lot about reversing biological age. But how do we actually know when it's working? In this conversation with Dr. Vera Gorbunova and Dr. Andrei Seluanov, they break down one of the most important — and most overlooked — questions in longevity science. The tools being used to measure cellular aging, starting with methylation clocks and now expanding into multiomics biomarkers, represent some of the most significant breakthroughs in the field. But as Dr. Gorbunova and Dr. Seluanov are honest enough to point out: they're not perfect. Especially when it comes to assessing any one individual. It's a critical distinction. The science is advancing. The markers are getting more sophisticated. And yet the gap between what we can measure at a population level and what we can confidently say about a single person remains one of the field's biggest open questions. Progress and limitation, existing at the same time. Explore the full conversation, out now on all major streaming platforms.
