In this episode of Up One, hosts Sawyer Stone and Dr. Bill Andrews are joined by world-renowned sexual health expert Dr. Amy Killen to explore the profound link between physical intimacy and biological longevity. The conversation breaks down the "four pillars" of sexual health—the mind, hormones, blood flow, and pelvic support—while highlighting research that suggests regular sexual activity can lower all-cause mortality by 50%. From the benefits of oxytocin and nitric oxide to emerging regenerative treatments like shockwave therapy and stem cells, the trio discusses how maintaining sexual vitality isn't just about reproduction; it is a critical biomarker for overall physical, mental, and immune health. Challenging the myth that sexual decline is an inevitable part of aging, Dr. Killen provides actionable advice on lifestyle choices, supplements, and the importance of open dialogue to help listeners reclaim their health span.

In this frank discussion on Up One, host Sawyer Stone is joined by Dr. Bill Andrews and longevity physician Dr. Sandra Kaufmann to demystify menopause, an event Dr. Kaufmann calls "a canary in the coal mine" for a woman's aging process. They debate the underlying cause, with Dr. Andrews questioning if it's a random genetic accident linked to 'Mitochondria Eve' or a mysterious, non-linear timing mechanism. Dr. Kaufmann offers the view that it's fundamentally ovarian failure driven by high metabolic demands , and they address common symptoms like osteoporosis, fatigue, and the surprising link between estrogen decline and LDL cholesterol. They also discuss the crucial timing of hormone replacement therapy and the non-linear "cobweb" of interconnected molecular pathways that influence a woman's transition.

In this episode of Up One, hosts Sawyer Stone and Dr. Bill Andrews pull back the curtain on the world of scientific publishing and health claims. Dr. Andrews explains that a standard meta-analysis is insufficient because the peer-reviewed literature is riddled with flawed or even fabricated data, often fueled by the pressure to "publish or perish" or by commercial bias. He defines critical meta-analysis (CMA) as the essential skill needed to determine a study's true credibility by examining experimental design, statistical integrity, and the common sense of its conclusions. Listeners will learn how easy it is to mistake correlation for causation and why a single "Betty White test" is often more trustworthy for assessing age reversal than quantitative biomarkers alone.
