The Longevity Paradox: Medicine Meets Silicon Valley
'For without friends, no one would choose to live.' - Aristotle
Jeffrey Benabio, MD, MBA
Last year, Bryan Johnson, a 46-year-old tech founder, spent 2 million dollars on a regimen that included monthly plasma transfusions from his teenage son. Why? Well, we live in an age when the wealthy inject themselves with young blood, undergo elaborate hormone replacement protocols, get infusions of NAD+, and gobble metformin pill-packs to optimize their biological age. The sell is seductive: Death is evitable. Aging is curable. And with enough money, one can live to be old and healthy.
The venture capital bets might be recent, but the yearning is ancient. Herodotus wrote in the 5th century BCE about special waters the long-lived Macrobians drank and bathed in — waters that not only extended life but left their skin "glossy and smooth." Later, Alexander the Great, in his conquests, was said to have been on a quest to find the "Water of Life." He died at 32, which is probably why his product isn't a popular supplement on Amazon today. Lucas Cranach's "The Fountain of Youth," painted in the late Medieval period, shows old and infirm patrons swimming in magical waters and emerging vibrant and young on the other side. Perhaps those waters had rapamycin-producing Streptomyces growing in it — which is a top seller today.

Behind the tempting pitch to live forever lies an uncomfortable question: Is this medicine? Should we be testing testosterone on an athletic 23-year-old? Or continuously monitor glucose for a healthy adult with no signs of diabetes? Few doctors would order these for patients, and fewer payors would pick up the tab if they were ordered. This is the disconnect between medicine and entrepreneurs.
"The medical system is so patronizing," said a young venture capitalist on a popular startup podcast I was listening to. He was complaining about how doctors resist ordering MRIs or specialized tests because we doctors "think patients are idiots." We do not. He's missing the point that, as a healthy 30-something, medicine is not resourced to help him with wellness requests. Who should pay for his requested MRI? Who would interpret the results? We physicians cannot keep up with the demand for services from those who need us acutely. We've no plan for absorbing a new generation of the "worried well" — better named the "ambitious well" — while also caring for their boomer grandparents.
We have a critical shortage of primary care physicians; one that will only worsen as our population ages. The Association of American Medical Colleges projects a shortage of up to 40,400 primary care doctors by 2036. What happens if a portion of that workforce begins dedicating their time to monitoring biomarkers and fine-tuning supplement regimens for patients who are not sick?
Healthcare resources — physicians' time, diagnostic equipment, laboratory services — are finite. Every hour we spend with a healthy person seeking optimization is an hour not spent with a patient who is ill. For every primary care physician giving up their practice for a cash-paying longevity clinic, there will be 2000 or so patients who now have to be redistributed onto already burdened practices. When healthy 35-year-olds can get same-day MRIs at boutique practices while my father-in-law waits nearly 2 months for an MRI to characterize a renal mass seen on ultrasound, we've failed.
Caring for cash-paying patients who can sit with you for an hour is preferable to the daily grind of 15-minute appointments for patients who actually need an hour of your time. Why shouldn't docs get to choose? For one thing, our training is publicly funded. Taxpayer dollars pick up the tab for more than $20 billion in graduate medical education every year. It seems not quite right that this education doesn't at least in part serve the public who funded it.
Despite these concerns, we should acknowledge the import of the longevity movement. Prevention is indeed better than cure. Early intervention can avert costly medical problems. And individuals have a right to pursue health optimizations they value, using their own resources.
The question is, how should longevity medicine relate to our broader healthcare system and societal priorities? I think transparency is essential. Longevity interventions should be clearly labeled based on the strength of supporting research. It's the standard we adhere to every day in practice. We also need to be clearer about necessity versus enhancement. Insurance coverage and public resources should prioritize interventions that address or prevent disease. Enhancement services should be demarcated as distinct from necessary medical care.
Physicians working in longevity medicine might also acknowledge some societal obligations. Perhaps consider devoting a portion of their practice to underserved populations or contributing to research that benefits the broader public, not just those who can afford boutique services. We also surely must address the structural factors that push physicians toward concierge practices. If doctors are fleeing due to administrative burden and time constraints, improving those would help ensure care remains accessible to all.
Lastly, we might recognize that the best determinants of longevity operate at the population not the individual level. Clean air and water, safe neighborhoods, access to nutritious food, and strong social connections likely do more to improve the health and longevity of a population than any supplement or monitoring device.
Realizing the promise of longevity medicine requires more than scientific breakthrough; it demands clarity about how these advances should be distributed and what values should guide their application.
As physicians we face a choice: Should we allow longevity to become another domain where privilege determines outcomes? Or could we build a system where the benefits of extended healthy life are available to all?
Since Herodotus and after nearly 2500 years of searching, we still haven't found the water of life. Or maybe Aristotle actually discovered it just a few years later: gymnastics, moderation in food and drink, and good friends. It's hard to raise a series A with that pitch though.

Insurers Pledge to Ease Controversial Prior Approvals for Medical Care
Facing regulatory crackdowns and intensifying criticism from patients and doctors, the nation's biggest health insurers said on Friday that they would retreat from tactics that have delayed medical care and led at times to denials for necessary treatments. For years, the widespread practice known as prior authorization has vexed patients who might not have been notified until the day of surgery whether a procedure would be covered by their insurance or if a prescription medicine would be denied for no clear reason. Insurers often send unintelligible form letters, leaving patients to puzzle out the basis for the denial or what their next steps should be. Patients may delay or even abandon necessary medical care because they may not even be aware that they can appeal the decisions. Lawmakers, regulators and public outrage have drawn attention to abuses of the system, leading to mounting calls for reforms. Insurers have also been the target of myriad lawsuits, some of which attributed patient deaths to those denials and delays. The murder of Brian Thompson, a UnitedHealthcare executive, last December renewed criticisms of the tactic, unleashing a barrage of complaints that the practice was deployed to avoid covering care. 'Prior authorization is a huge issue for people who are in managed care plans because it is one of the ways plans use to control their costs,' said David A. Lipschutz, co-director for the Center for Medicare Advocacy. He pointed to several studies showing that insurers may have inappropriately denied care, particularly in private Medicare plans. Various reports from federal regulators and researchers show that the vast majority of appeals are successful. Want all of The Times? Subscribe.

Neuroscientists find brain cells that explain why stress keeps you up at night
If your anxiety before a big test or a high-stakes presentation has ever kept you up at night, you can rest easier knowing that scientists are trying to get to the bottom of things. A new study published this month in The Journal of Neuroscience explores how stress interferes with sleep, causing cascading negative effects on memory and other cognitive processes. By pinpointing the specific neural mechanisms involved in stress-related memory problems and sleep disruptions, scientists hope to figure out stress-zapping treatments in the future. A group of researchers from the University of Pennsylvania School of Medicine's Chronobiology and Sleep Institute simulated human stress in lab mice, restraining the animals so they couldn't move. They then observed the animals' neural activity while they slept and gave the mice a spatial memory test. Much like a human stressed out before a big test, the mice slept poorly and showed memory deficits. The researchers went on to simulate the effects of the stress scenario without actually restraining the mice. By activating neurons that release the stress hormone corticotropin in a specific part of the hypothalamus known as the paraventricular nucleus, the research team stressed the mice out and went on to observe the same sleep and memory issues as if the animals had actually been restrained. When they blocked the same stress hormone-releasing neurons during the stress-inducing event, the mice slept a little better and had significantly less trouble during their spatial memory test – a hopeful finding understanding how to mitigate the problems that stress creates in the human brain. The researchers called the findings on the pathways of corticotropin-releasing hormone neurons in that region of the hypothalamus 'an important step toward improving sleep and ameliorating cognitive deficits associated with stress-related disorders' – a conclusion that anyone tired of having that one same stress dream can definitely get behind.

Eating more fruits and vegetables linked to surprising effect on sleep
Your daily meal selections could influence the quality of your sleep, new research says. A study from the University of Chicago Medicine and Columbia University found that increasing your intake of fruits and vegetables could help promote more restful sleep. Previous research has shown that people who lack quality sleep may be more likely to indulge in unhealthy foods that are high in fat and sugar — and now this new finding sheds more light on how consumed foods impact sleep. In the small study — which was published in "Sleep Health: The Journal of the National Sleep Foundation" — 34 healthy young adults reported their daily food consumption and wore a tracker to measure how often they woke up or changed sleep patterns during the night, according to a press release. Those who reported eating more fruits and vegetables during the day were found to have "deeper, more uninterrupted sleep." Greater amounts of healthy carbohydrates, like whole grains, were found to have that same benefit, the study found. "Dietary modifications could be a new, natural and cost-effective approach to achieve better sleep," said co-senior author Esra Tasali, MD, director of the UChicago Sleep Center, in the release. "The temporal associations and objectively-measured outcomes in this study represent crucial steps toward filling a gap in important public health knowledge." Based on the study findings, the researchers concluded that people who eat at least five cups of fruits and veggies per day could have a 16% increase in quality of sleep compared to those who eat none of those foods. "Small changes can impact sleep. That is empowering — better rest is within your control." "16 percent is a highly significant difference," Tasali said in the release. "It's remarkable that such a meaningful change could be observed within less than 24 hours." "Based on current data, the experts confidently advise that regularly eating a diet rich in complex carbohydrates, fruits and vegetables is best for long-term sleep health," the release stated. The American Heart Association provides the following examples of fruit and veggie servings that equate to 1 cup of produce. Dr. Chelsie Rohrscheib, head sleep expert at Wesper in Michigan, said that most sleep professionals recognize that a healthy diet supports overall well-being, including sleep quality — "so the findings of this study are not entirely unexpected." "However, it's important to note that this was a relatively small study composed primarily of young adult male participants, which limits generalizability," Rohrscheib, who was not involved in the study, told Fox News Digital. "While the results were statistically significant, the overall reduction in sleep fragmentation was modest, about 16%." The study was also observational in nature, she noted, which means it lacked the control of a randomized trial. "Ideally, future research would compare a group consuming a fruit- and vegetable-rich diet to a control group with limited intake to better establish causality," the doctor added. The researchers plan to conduct more studies to confirm that eating produce causes better sleep and to determine the "underlying mechanisms of digestion, neurology and metabolism" driving this impact, the release stated.
