If you want to meaningfully impact aging in America, start with obesity—few things erode longevity and quality of life as profoundly, accelerating the biological aging process and fueling nearly every major chronic disease. Obesity alone is linked to 13 types of cancer and cuts life expectancy by 3–10 years, depending on severity. It promotes DNA damage and accelerates our fundamental aging process—often measured by epigenetic age. It’s one of the principal differences between the U.S. and many of the world’s longest-lived nations. We’re overfed but undernourished. 60% of all calories Americans consume come from ultra-processed foods that: • Fail to induce proper satiety, pushing us to overeat. • Remain cheaper than whole foods, economically incentivizing the least healthy choices. • Hijack our dopamine reward pathways, reinforcing addictive eating behaviors. This trifecta—no satiety, low cost, and built-in addictiveness—keeps us in a cycle of poor health outcomes and runaway healthcare costs. But caloric excess is only part of the problem—we are also nutrient-deficient. Low omega-3 levels—affecting 80 to 90% of Americans—carry the same mortality risk as smoking. Vitamin D deficiency—easily corrected—compromises immune function, cognition, and longevity. Nearly half of Americans don't get enough magnesium—impairing DNA repair and increasing the risk of cancer. We are not solving these problems—we are medicating them. The average American over 65 takes five or more prescription drugs daily—stacking interactions that compound in unpredictable ways. We must start treating physical inactivity as a disease. It carries the same mortality risk as smoking, heart disease, and diabetes. Going from a low cardiorespiratory fitness to a low normal adds 2.1 years to life expectancy. By age 50, many Americans have already lost 10% of their peak muscle mass. By 70, many have lost up to 40%. This isn’t just about looking strong. It’s about survival. • Higher muscle mass means improved insulin sensitivity - it means a 30% lower mortality risk. • Grip strength is a stronger predictor of cardiovascular mortality - the number one cause of death in the United States - than high blood pressure. • The strongest middle-aged adults have a 42% lower dementia risk. And yet, we treat resistance training as optional. It is not. It is the most powerful intervention we have against aging including increasing muscle mass, strength and bone density. Hip fractures alone kill 20–60% of older adults within a year. This is a death sentence we can prevent with resistance training - which has been shown to lower fracture risk by 30-40%. The current RDA for protein is too low for older adults. Studies have shown when it's increased by half this reduces frailty by 32%, while doubling it, combined with resistance training, increases muscle mass by 27% and strength by 10% more than training alone. If we want to prevent muscle loss and frailty, we must update our protein recommendations and prioritize strength training. We must foster a culture of American exceptionalism built on daily, effortful exercise. Not as an afterthought. Not as a luxury. But as a non-negotiable foundation for aging, but also clear thinking, resilience, and even leadership. The body and brain are not separate. The consequences of poorly regulated blood sugar, sedentary living, and muscle loss are not just physical—they affect cognition, judgment, and resilience. We cannot medicate our way out of what we have behaved our way into. Grateful for the chance to share my voice at the Senate Aging Committee (@SenateAging). A special thank you to Senator Rick Scott (@SenRickScott) for making this opportunity possible.

New episode featuring Stanford professor, neurobiologist, and host of the incredibly popular Huberman Lab Podcast, Dr. Andrew Huberman (@hubermanlab). What makes Andrew truly exceptional is his ability to translate scientific findings into practical, actionable advice, enabling listeners to leverage new understandings of biology and neurobiology to improve their lives. In this episode, Dr. Huberman showcases his truly immense knowledge of the brain's dopamine system, which is incredibly central to many modern issues of motivation and attention that many of us struggle with. The public perception of Dr. Huberman's work often focuses on his unique distillations of protocols, but what I particularly enjoyed about this conversation was finding a common thread: the benefit of having an essential life philosophy of valuing "hard effort" over outcomes, something Andrew refers to as "forward center of mass." This podcast explains down to a neurobiological level why embracing discomfort can activate our motivation circuits, elevate dopamine and other catecholamine levels, and retrain brain regions like the anterior midcingulate cortex, ultimately growing our capacity for effort and striving at a fundamental level. A big thank you to Andrew for equipping us with this knowledge, enabling us to apply these insights for individual personal and professional growth.
