Your heart's rhythm holds the secret to your longevity—and most people are measuring the wrong thing. The Science Spotlight: Your Weekly Deep Dive Into Breakthrough Research I spent decades in believing that a low resting heart rate was the gold standard for cardiovascular fitness. I've learned that the real marker of physiological resilience isn't how slow your heart beats—it's how adaptable it is. Heart Rate Variability, or HRV, measures the variation in time between consec

There is no proven casual link between melatonin and heart failure. By Dr. Travis Smith, DO – Bio Precision Aging Medical Editorial Team A recent analysis presented at the American Heart Association (AHA) Scientific Sessions 2025 sparked headlines suggesting that long-term melatonin use may increase the risk of heart failure. But before we draw conclusions, it’s critical to understand what the study actually showed—and what it did not prove. Let’s unpack the findings, the li

By Travis Smith, DO A s physicians working in precision aging and longevity medicine, we’re constantly seeking evidence-based interventions that can meaningfully impact healthspan and lifespan. Recent landmark research from major academic institutions has revealed something remarkable: daily low-dose tadalafil may be one of the most underutilized longevity interventions available today. The Numbers Are Staggering A comprehensive study published in The Journal of Sexual Medic

Your weekly deep dive into breakthrough research At 63, I've witnessed too many colleagues and friends receive that life-changing call from their cardiologist—"We found blockages." But here's what I've learned through my own transformation and the latest scientific evidence: the most powerful intervention isn't the one that happens after your first heart attack. It's the strategic action you take years before any symptoms appear. The data is crystal clear, and frankly, revolu
