  • Here is the German TV show Galileo that Bill was featured in.


    From  German speaking forum member (@edward_sutherland), unfortunately the documentary isn't so generous


    • this documentary is basically mocking the idea of life extension, but in a humorous way without ill will. In German you would say  "spöttisch"
    • the reporters meet Bill on a day he must dread most,- his birthday!
    • what is being preached in the church of Perpetual Life, no prayers instead science!
    • the reporter complains about the cost of anti-aging products and later in the documentary complains about having to swallow so many pills a day.
    • the Gerontologist who looks over Bills bloodwork states that the results show a healthy person, but in no way can it be deduced that these values show a 21 year old instead of a 65 year old!
    • the idea that ingesting many pills will help much (Bill Faloon takes 100 a day) is disputed by the Gerontologist who warns of unknown side effects and is surprised that Bill is still alive.
    • the Gerontologist explains to the reporter that despite the results of scientific studies that Bill Faloon refers to showing possible anti aging effects, the use of the prescription drugs such as Rapamycin or Deprenyl is dangerous.
    • at the end of the documentary the moderator says that Bill Faloon is a pioneer and not a crackpot, who is risking his health for the goal of immortality. Someday age reversal will be possible, but the question is, will Bill Faloon still be around then?

  • From the Age-Reversal network email list, Bill's latest missive to the faithful :)

  • Another one from our own Brian and Bill. This is worth watching in its entirety, we get insights from Brian's deep experience in health and longevity, and exciting news from Bill on the state of the protocols.

  • Dr Rhonda Patrick has a wonderful channel where she interviews fellow biomedical researchers whose work has an impact on health and longevity. They all are good, but this recent one about sleep in particular, while long, is worth listening carefully to the entire podcast, the point being made and illustrated is how sleep is turning out to be the underpinning to all of health. 

    I'd put this in the category of Bill's 'House' analogy from recent talks. Before starting any of these interventions, have you got the basics in order? If your diet, exercise, sleep, hormones, BP and blood work isn't looking great then you probably shouldn't bother with the more advanced protocols. Go after the low hanging fruit first! Otherwise you're probably rearranging deck chairs on the Titanic and wasting time and money that could be spent getting the fundamentals straightened out. 


    For those of us who like text (myself included)

    Matthew Walker, Ph.D., is a professor of neuroscience and psychology at the University of California, Berkeley, and serves as the Director of the Center for Human Sleep Science. Formerly, Dr. Walker served as a professor of psychiatry at the Harvard Medical School.
    Walker's research examines the impact of sleep on human health and disease. One area of interest focuses on identifying "vulnerability windows" during a person's life that make them more susceptible to amyloid-beta deposition from loss of slow wave sleep and, subsequently, Alzheimer's disease later in life.

    Dr. Walker earned his undergraduate degree in neuroscience from the University of Nottingham, UK, and his Ph.D. in neurophysiology from the Medical Research Council, London, UK. He is the author of the New York Times best-selling book Why We Sleep: Unlocking the Power of Sleep and Dreams.

    Sleep as foundational bedrock for our ability to learn from experience

    In some ways, the highly conserved nature of sleep across the animal kingdom seems like a paradox: Whereas closing our eyes to sleep obviously leaves us and the rest of the animal kingdom vulnerable for long stretches of the twenty-four hour day, not sleeping must carry even more risk when we consider that it has not been weeded out in spite of this.

    Without sufficient sleep, our ability to learn – the acquisition of new memories – begins to rapidly break down. And yet, this is only one of the major roles we now appreciate that sleep has. In this episode, sleep expert Dr. Matt Walker describes how sleep is critical to learning and survival because it facilitates a process he likens to the input, storage, and transfer of data in a computer.


    Sleep preps the brain for information input
    The formation, or "encoding," of memories occurs when the brain engages with new information – ideas, actions, or images – and leads to the formation of a representation of this information in the brain. Sleep preps the brain so that it can assimilate this new information and lay down the framework for new memory traces. Without sufficient sleep – in particular, the slow wave sleep that occurs during the stage of non-rapid eye movement, or NREM – the brain's ability to receive new input is markedly impaired. This phenomenon has critical implications in students and has been observed when college students who were deprived of sleep experienced dramatic deficits in their ability to learn new information.


    Sleep facilitates information storage
    Sleep also facilitates the more permanent storage of new information that has been stored in the hippocampus – the region of the brain responsible for the formation and consolidation of short-term memories. Sleep that occurs after exposure to new information fulfills the role of the brain's "save button."


    Poor sleep, however, inhibits the brain's ability to form memories. Dr. Walker and his colleagues believe that this might be a quality of a time-limited capacity for hippocampal storage. Wakefulness that exceeds the typical 16-hour day might effectively outstrip this region's capacity for short-term storage of information.


    Sleep provides a mechanism for information transfer and the formation of long-term memories
    The intake and storage of mere short-term information are insufficient for optimal learning, however. The final, and perhaps most critical, way in which sleep aids in learning is that it provides a mechanism by which new information can be permanently stored – the formation of long-term memories via transfer to the brain's cortex, where they can be retained and then retrieved for future use. Without this transfer phase, we run the risk of hippocampal-associated memory impairment – a problem readily observed in older adults who experience loss of slow wave sleep and subsequently demonstrate difficulty retaining memories overnight.


    A fascinating new strategy to selectively enhance memories during sleep

    When we sleep, memories and their associated events acquired during periods of wakefulness are reactivated. Essentially, the brain "replays" the events that occurred prior to sleeping, a process which stabilizes memories by serving as a pruning mechanism, selectively strengthening strongly associated memories and weakening weakly associated ones. A surprising fact is that this process can be amplified by "cueing" the reactivation during sleep with sub-awakening threshold sounds, odors, or other sensory cues – based on the context of the learning received the previous day.

    A common thread between aging-associated loss of slow wave sleep, accumulation of amyloid-beta, and impairment of hippocampal-dependent of memory

    The decline of deep, slow wave sleep begins much earlier in life than most people would expect, with losses occurring as early as the late 20s. By the time a person reaches 50, they've lost roughly half of their deep sleep, and by the time they're 80, deep sleep brain waves are almost undetectable, according to Dr. Walker. Small wonder, then, that aging is accompanied by cognitive decline and substantive memory loss, especially in age-related disorders such as Alzheimer's disease.


    Sleep disruption is integrally associated with Alzheimer's disease and its pathophysiology, with characteristic changes in sleep emerging well before the clinical onset of the disease. A key player in the development of Alzheimer's disease is amyloid-beta, a toxic protein that aggregates and forms plaques in the brain. Insufficient sleep increases the production of amyloid-beta, and amyloid-beta deposition, in turn, impairs sleep – in a vicious, self-perpetuating loop.


    Recent studies indicate that the lion's share of amyloid-beta accumulates in the medial prefrontal cortex – an area Dr. Walker refers to as the "electrical epicenter" for the brain waves of deep, slow wave sleep – and the severity of accumulation significantly predicts the degree and extent of cognitive decline associated with Alzheimer's. The accompanying loss of deep sleep impairs overnight memory consolidation and retention, further impairing hippocampal-dependent memory consolidation.


    Dr. Walker's research suggests that quality of sleep in later life may actually confer a kind of resilience, staving off the cognitive decline commonly associated with aging.


    Sleep facilitates the brain's self-cleaning mechanism: the glymphatic system
    One of the reasons slow wave sleep, in particular, seems to be so important is because it facilitates the proper functioning of the glymphatic system, a system crucial for clearing the brain of metabolites and other waste. The glymphatic system comprises a vast arrangement of interstitial fluid-filled cavities surrounding the small blood vessels that serve the brain. These perivascular structures are formed by astroglial cells and expedite the removal of proteins and metabolites from the central nervous system. During sleep, these interstitial spaces increase by more than 60 percent. This allows a "flushing" operation in which waste products can be more efficiently eliminated. The glymphatic system also facilitates the distribution of essential nutrients such as glucose, lipids, and amino acids, as well as other substances, such as growth factors and neuromodulators.


    Our biological need for sleep may reflect a need for an essential downtime that enables elimination of potentially neurotoxic waste products, including amyloid-beta, a toxic protein that aggregates and forms plaques in the brain. During deep, slow wave sleep, the glymphatic system clears as much as 40 percent of the total amyloid-beta accumulation. A mere 36 hours of sleep deprivation, however, increases amyloid levels by 25 to 30 percent. This fascinating emerging story on a crucial function of sleep is just one more incremental discovery that helps us understand the existence of sleep in the midst of the evolutionary conundrum mentioned earlier. While many things may help us prevent the build-up of amyloid plaques by boosting our capacity for glymphatic clearance — such as exercise and adequate intake of omega-3 — by far, the most important factor is sufficient sleep, especially slow wave sleep.


    Much of this underscores the need for developing non-pharmacological strategies for addressing sleep loss or enhancement of slow wave sleep. A strong candidate is transcranial direct current stimulation, a non-invasive, brain stimulation treatment that uses direct electrical currents to the brain to enhance deep sleep and improve memory capacity in older adults, and even doubling it in young adults. Other strategies involve auditory closed-loop stimulation – the delivery of tones in synchrony with endogenous slow wave oscillations in the brain – and slow, rhythmic bed rocking.

    Loneliness as a contagion promoted by sleep loss

    Another, somewhat troubling, consequence of sleep deprivation is that it triggers the onset of a "loneliness phenotype." Lack of sleep induces critical changes within the brain, altering behavior and emotions, while also disturbing essential metabolic processes and influencing the expression of immune-related genes. The end result is that people who are sleep-deprived avoid social interaction. This asocial profile is recognizable by other people, who, in turn, shun the sleep-deprived people in a psychosocial loop that perpetuates in a vicious cycle of loneliness and other mental health disorders.


    Impairment of glucose regulation and the promotion of an obesogenic profile

    For anyone who habitually tracks their glucose levels, the importance of sleep can quickly become obvious. As Dr. Walker reveals in this episode, even a few days of impaired sleep, particularly loss of slow wave sleep, manifests itself in a rather remarkable way: a change from potentially good glucose management, to something akin to a rapid onset of pre-diabetes. This is real-world observable.


    In fact, sleeping less than seven hours per night itself has been associated with either having diabetes or eventually developing the condition. The problem is multifactorial. Not only does lost sleep cause our pancreatic beta islet cells that produce insulin to become less responsive to glucose signals, but muscle and other cells also become less responsive to insulin. These adverse changes from sleep loss are then compounded by deleterious alterations in the body's levels of appetite hormones leptin and ghrelin, which lead to, as Dr. Walker terms it, an obesogenic profile of energy consumption as a consequence of potentially chronic sleep loss.


    Sleep plays a vital role in maintaining optimal mental and physical health throughout life. Listen to Dr. Walker explain how sleep is critical to our survival.

  • Breaking News: Robust Mouse Rejuvenation only 3 years away

    Aubrey has always been on the more pessimistic side of Longevity Escape velocity timeframe, Ray Kurzweil is predicting 9 years I believe from 2018, Aubrey was 25 years, in this video he reveals he is now predicting 18 years.

  • Great talk from Anand Patel on what he's learned for longevity. I'd emphasize his point about the importance of consistency - I've also found the value of this. One it's easier, just put some health habit on autopilot. Second is it's a compounding effect.

  • Interview with Aubrey De Grey. BrianMDelaney  of interest is work going on using low dose ordinary antibiotics, of all things, successfully targeting senescent cells. Start at 20:15 (video should point to that start). Sounds like it was in culture however, perhaps not in human or mouse models 

  • Very good interview with Aubrey, around 37:00 is a discussion of some specific mitochondrial effects of NAD treatment. 

  • Judy Campisi from the Buck Institute discussing senescent cell treatment. Very interesting discussing of the nuances of senolytics, brings into question perhaps targeting senescent cells as people are doing her.

  • Aubrey and Bill having a discussion about life extension. 

  • Cracking & reversing the aging clock, David Sinclair from Harvard. He's been doing a lot of NAD research. Here's a video about his view of the root cause of aging. 

  • Much longer (over two hours) audio only interview with Rich Roll, much more in depth, and worth listening to. We're not the only ones thinking that comprehensive age reversal is not too far in the future.

  • Well done interview of Aubrey de Grey, though poor Aubrey gets pushed into drinking Vodka by his Russian host, though he clearly doesn't want to. I hate when people push alcohol on me, I just say no :)

    Of note: Aubrey now predicts a 50% chance of Longevity escape velocity in 17 years.

  • The best interview with Sinclair I've seen. Some key points from this


    • NR & NMN should be kept cool or refrigerated. If not they can turn into a different compound you definitely do not want to take. 
    • Resveratrol should be kept in a dark place, if it turns brown it's not effective. 
    • Trans-resveratrol is better than Resveratrol.
