Longevity is having a moment. From NAD+ infusions and peptide therapies to “biological age reversal” clinics, the biohacks and promises are everywhere. But ask the physicians at Precision Health Concierge Medicine in Sarasota what actually extends a healthy life, and the answer is considerably less glamorous. “We’re just practicing really good primary care and individualizing it to each patient,” says Dr. Sheena Spielberg. “Longevity medicine is a natural extension of that.” The approach centers on a simple but consequential distinction: lifespan versus healthspan—the number of years lived actively and well. Average U.S. life expectancy is roughly 78, but most Americans spend their final 13 years managing chronic disease. Precision Health works to close that gap through early screening for cardiovascular disease, cancer, metabolic dysfunction and cognitive decline, combined with personalized interventions on diet, exercise, sleep and emotional well-being. “It’s the wellness wild west out there,” says co-founder Dr. Patrick Mullen. “People are always chasing the next best thing, when most of it comes back to doing proven, foundational things extraordinarily well.” That requires time—something traditional insurance-based medicine rarely allows. Co-founder Dr. Zyad Asi frames it simply: “We’ve dedicated our lives to researching the most current medical knowledge to help our patients, and we’re not just doing something because it’s popular. We’re treating the whole person to slow down the aging process so people can keep playing with their grandkids.” —S.Lubow  precisionhealth.com
