The Optispan Podcast with Matt Kaeberlein

Exploring the potential of age reversal through E5 formulation, rejuvenating effects of young piglet blood exosomes, controversy over lifespan extension claims, analysis of rat survival data, comparison of longevity interventions in rodents, and ethics of reversing biological age.

Expert in AI and aging, Mitchell Lee, discusses using Warm Bot for aging experiments, genetic variations' impact on longevity interventions, rapamycin effects on fly development, unbiased data collection with Wormbot, shared pathways in aging between C. elegans and humans, challenges in longevity research, optimizing drug dosages for worm experiments, exploring lifespan-extending molecules beyond rapamycin, and navigating funding challenges in research.

Attendees included former Speaker of the House Newt Gingrich, Republican Congressman Gus Bilirakis, and Democratic Congressman Paul Tonko. We have decided to include Matt's presentation on our channel because we believe it delivers a valuable message. Healthcare has historically taken a piecemeal approach to diseases, addressing ailments in isolation. While this method has been successful at curing and sometimes even eradicating multiple diseases, it has its limitations. Aging is the single greatest risk factor for many of the chronic diseases we worry about in later life—think cancer, Alzheimer's disease, diabetes—and involves a complex interplay of molecular, cellular, and physiological changes that underlie a myriad of health conditions. There is a reason that your average 80-year-old has more health problems than your average 18-year-old. As our understanding of human biology deepens, it is becoming increasingly evident that we need to broaden our focus beyond individual diseases and incorporate the biology of aging into strategies for improving human health and resilience to disease. Achieving this paradigm shift towards addressing the fundamental processes of aging, which will require interdisciplinary collaboration between scientists, clinicians, policymakers, and the public, will give us the potential to mitigate multiple age-related diseases simultaneously. In this episode, Matt covers how we got here, the differences between 19th and 21st century medicine, and the importance of targeting the biological aging process to create transformative results in tackling healthcare challenges. He also discusses policy reforms that would be useful for the cause, including changes to FDA regulation, a rethinking of insurance reimbursement, and how he would reslice the federal funding pie.

I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.

But the longevity field runs on way more than just science. It takes a village—a community of researchers, engineers, entrepreneurs, investors, regulators, and beyond who believe in the value of tackling the biology of aging as a crucial strategy for extending healthy lifespan—to create tangible results that benefit as many people as possible. At Optispan, we're eager to support and interact with the many levers that keep this machine going. One of these is the Alliance for Longevity Initiatives (A4LI), a nonprofit organization focused on catalyzing social and political action that will benefit the longevity field. In this episode, Matt chats with A4LI founder, president, and CEO Dylan Livingston about forming a bipartisan longevity science caucus, redirecting funding towards geroscience research, and engaging with policymakers to help them understand the importance of transitioning towards a proactive healthcare model. Dylan, who founded A4LI in 2021, served as a field organizer for President Joe Biden's 2020 presidential campaign. He also worked as a community organizer for Organizing Corps 2020, where he registered hundreds of Democratic voters in Pennsylvania for the 2020 presidential compaign. Dylan graduated from Haverford College with a B.S. in physics and a minor in economics. Matt joined the A4LI Board of Directors in 2024.

DEXA scans utilize two different energy levels of low-dose X-ray beams—one absorbed mostly by soft tissue, and the other absorbed mainly by bone—to differentiate between bone, fat, and lean tissue. In so doing, they provide noninvasive and detailed information about bone health, risk of osteoporosis or fractures, and body composition. While medical practioners typically perform DEXA scans on the lower spine and hips, they can also perform DEXA scans on the whole body for the purposes of early detection and intervention. In our multi-part DEXA series, we go deep into DEXA scans: what they measure, how to interpret them, and how to use information from your own DEXA scan for healthspan optimization. This week we're on Part II, where we analyze the DEXA scans of Matt and Optispan Lead Healthspan Analyst and certified personal trainer Nicholas Arapis. We unpack the nuances of the various metrics a DEXA scan measures, discuss potential noise in the results, and hear from Nick about what he would tell Matt to do if he was coaching Matt based on his DEXA scan results.

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: The Importance of Body Composition & Ways YOU can measure it | 21 - HSM #3: https://youtu.be/gM3aYTMsqNI We talk a lot about making a shift from reactive disease care—a 20th century healthcare mindset—to preventative and proactive health measures designed to optimize longevity and healthspan before disease sets in. Rather than waiting for chronic conditions to manifest and treating their symptoms post hoc, we encourage investing resources in preemptive care and empowering individuals to act as partners with healthcare providers in their own wellbeing. Preventative medicine can feel like a lot—cancer screenings, for example, are crucial for early detection and treatment, but can be logistically and emotionally daunting. But proactive healthcare doesn't always need to be complicated. In this episode, Matt goes through what he sees as low-hanging fruit in preventative medicine: simple steps that lend themselves to straightforward measurement, are easy to improve without invasive intervention or drastic lifestyle changes, and will pay dividends in increasing our overall health.

Prescription drugs have multiple uses beyond their intended purpose, some linked to lower mortality rates. Research explores statins, NSAIDs, PDE5 inhibitors, estrogen, vaccines, and antibiotics for potential longevity benefits. Study highlights correlations between drug usage and all-cause mortality, advocating for cautious prescription practices and unbiased research approaches.

They serve as both a protective mechanism against cancer, preventing damaged cells from uncontrollable replication, as well as a contributor to tissue dysfunction and age-related pathologies such as cardiovascular disease, neurodegenerative disorders, and diabetes. The precise mechanisms that underlie senescence and its contributions to the aging process remain areas of ongoing investigation and debate. In this episode, Matt chats with Sapere Bio co-founder and CEO Natalia Mitin about measuring cellular senescence, using those measurements in the clinic, and the complex and heterogeneous role of cellular senescence in aging and disease. They also discuss Natalia's personal experiences using rapamycin off-label to improve energy levels and immune function, the importance of monitoring biomarkers when using off-label medications, and Natalia's thoughts on "rapamycin for all". Prior to co-founding Sapere Bio, Natalia served as an assistant professor at the University of North Carolina at Chapel Hill's Department of Pharmacology. She spent over two decades developing assays for use in cancer research. She holds a B.S. in chemical engineering from the Mendeleev Institute for Chemical Technology and a PhD in biochemistry and molecular biology from Bowling Green State University. Optispan uses the SapereX test in its healthspan optimization program.
