The Optispan Podcast with Matt Kaeberlein
Optispan
Optispan is a vision for what health should be.
The typical person gives up 10-20 years of quality life in exchange for disability, frailty, and early death. We call this "the lost decade". Time that should be spent with loved ones doing the activities you enjoy are instead spent suffering from multiple diseases and taking a cabinet full of medications that probably do as much harm as good.
We believe that the current practice of medicine is disease care, not health care. We believe that everyone can get closer to their own optimal healthspan.

CAR T Cells: The Ultimate Anti-Aging Solution? | 16 - Longevity This Week #2
Subscribe to our channel: https://www.youtube.com/@optispan
While scientific papers are generally considered trustworthy sources of information, it's important to approach them with a critical mindset and to avoid blindly accepting their claims. The peer-review process, which helps ensure high research quality, is not foolproof. Errors or biases can slip through the cracks. In reading a paper, we should independently evaluate the evidence, scrutinize the methodology, and reflect on alternative interpretations of the data. Considering the influence of funding sources, conflicts of interest, and the potential for selective reporting can also help in maintaining a healthy skepticism about new information.
In this episode of Longevity This Week, Matt takes us through a recently-published paper about the effects of senolytic CAR T cell therapy on the aging process in mice to help us figure out whether the paper's claims hold water. He also analyzes a BBC article describing the findings. Popular press adaptations of the scientific literature often serve as a useful bridge between the complex world of research and the general public, but can be misleading in their attempts to make science accessible. They might, for example, inadvertently distort or oversimplify findings, exaggerate the significance of results, or selectively report research while ignoring contradictory or inconclusive evidence from other sources. We hope this episode will encourage viewers to approach science communication with a discerning eye, and to stay vigilant, curious, and open-minded in learning about the latest discoveries and developments.

Hi, I'm Matt Kaeberlein. 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.
On this channel I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these videos helpful!

Current Healthcare ISN'T CUTTING IT: How Optispan is REVOLUTIONIZING it |15 - Healthcare Medicine #1
Subscribe to our channel: https://www.youtube.com/@optispan
At its best, healthcare isn't just about extending lifespan—it's also about enhancing the vitality of our years. Over the last century, the healthcare system has made enormous strides in keeping sick people alive. The next step is to use proactive, preventative healthcare to stop them from getting sick at all. The Lost Decade—the 10 or so years that many people spend suffering from poor health and/or disability in older age—doesn't have to be a given.
In this episode, Matt discusses why he left academia to help start a healthcare revolution, why sickness and decline don't have to define our final years, how decades of geroscience research have informed his views of healthcare, and what he thinks healthspan optimization should look like.

Longevity Science 2024: New Insights on "The Hallmarks of Aging" & What They Mean | 14 - LS #5
Subscribe to our channel: https://www.youtube.com/@optispan
Over a decade ago, five researchers published a paper proposing the Hallmarks of Aging paradigm: a set of cellular and molecular processes that underlie the aging process in different organisms. These hallmarks encompass a range of interconnected pathways, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, disabled macroautophagy, deregulated nutrient signaling, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, chronic inflammation, and dysbiosis. Together, the hallmarks contribute to the gradual decline in physiological function and increased susceptibility to age-related diseases that occurs with age, and provide a framework for understanding how we age.
In this episode, Matt takes us through a quick download of each hallmark of aging, talks about some of the paradigm's shortcomings and limitations, and discusses the implications of the Hallmarks of Aging paradigm for the geroscience field.

University of Arizona Assistant Professor of Molecular and Cellular Biology George Sutphin runs a lab that investigates genetic determinants of longevity, the effects of kynurenine-based interventions on lifespan, and environmental regulators of the aging process. George, who was an aerospace engineer before he discovered the promise of geroscience, completed his PhD at the University of Washington and worked as a postdoctoral associate at the Jackson Laboratory prior to his current faculty position. He currently serves as Chairperson of the American Aging Association.
We sat down with George to talk about his research, including the effects of caffeine on lifespan and, more recently, his discovery of a new metabolite with the ability to greatly extend lifespan when given late in life. We also discuss George's thoughts on biological age clocks, his own healthspan optimization protocol, and much more.

Transforming Our Understanding of Healthcare Through Geroscience | 11 - LS#4
Subscribe to our channel: https://www.youtube.com/@optispan
Everything we talk about on The Optispan Podcast has geroscience at its root, so we decided to make an episode about it. Geroscience is the study of the mechanisms connecting biological aging with disease and disability. The term first appeared in the scientific literature around 2008, and its use has steadily increased since as researchers have discovered more about the aging process and its impact on our health. While it's clear that aging biology is at the root of the diseases and disabilities that most people get sick with and die from in their later years, it's been a challenge to get the field the traction and support that other fields enjoy, in part because we are used to a "disease care" model of waiting until people get sick and only then addressing their symptoms and/or curing their disease.
In this episode, Matt dives into the geroscience hypothesis and how it underpins the way we age, entrenched cultures in industries from drug development to insurance to regulation, and why he's excited to create a geroscience-inspired disruption in the medical and healthcare industries.

What a 93-Year-Old Rowing Champion Can Teach Us About Aging Well | 10 - Longevity this Week #1
Subscribe to our channel: https://www.youtube.com/@optispan
Defining "healthspan" & its role in living longer: https://www.youtube.com/watch?v=cI6CNFeBl88
Longevity This Week is a series of episodes discussing new findings or articles relevant to geroscience, longevity, and healthspan that may have popped up in the news.
This week we're featuring Richard Morgan, a 93-year-old rowing champion whom the Washington Post recently described as being "as fit as a 40-year-old". We talk about Richard's diet, exercise routine, and other aspects of his lifestyle that may have led to his enviable state in older age. We also discuss a recent Wall Street Journal article about how Americans are spending more of their lives in poor health, and about how "sickspan"—the amount of time we spend sick near the end of our lives—might change in years to come.

Understanding Aging & Disease and How They're Related: https://www.youtube.com/watch?v=94_Rqe2m1C0&feature=youtu.be
Biological age—that is, how old your cells and tissues are based on physiological function—is a multifaceted and intricate concept that transcends numerical representation. Unlike chronological age, which refers simply to the number of years you have been alive, the concept of biological age delves into the dynamic interplay between physiological processes, genetic predispositions, and environmental influences that collectively shape an individual's health trajectory. Geroscientists are currently studying the biological mechanisms that might impact your biological aging rate and perhaps reverse some of the functional declines that accompany aging.
