Aging naturally causes anabolic resistance, making the body lose muscle and absorb and utilize dietary protein less efficiently.

"As we age, we naturally lose muscle and become less efficient at absorbing and utilizing protein. There's actually a term for this: anabolic resistance." (said at 0:42:55)

The speaker's statement accurately summarizes age-related sarcopenia and anabolic resistance. Anabolic resistance is the established physiological term for the reduced capacity of skeletal muscle in older adults to stimulate muscle protein synthesis in response to dietary protein/amino acid ingestion and other anabolic stimuli.

  "Sarcopenia, the age-related loss of skeletal muscle mass and function, is primarily caused by anabolic resistance, which is the blunted stimulation of muscle protein synthesis (MPS) and impaired suppression of muscle protein breakdown following anabolic stimuli such as feeding."

Chronic traumatic encephalopathy (CTE) can continue to progress and worsen even after repetitive head trauma has ceased due to an ongoing feed-forward neuroinflammatory process.

"You can induce that shift from head trauma, for example. That's why these football players with chronic traumatic encephalopathy, encephalopathy continue to worsen once they've stopped after playing football. Look at Muhammad Ali: quit boxing, stopped the head trauma, but continues to worsen once this process has taken hold." (said at 1:03:52)

CTE is recognized as a progressive neurodegenerative disease triggered by repetitive head impacts, where primary trauma initiates secondary chronic cascades—prominently sustained neuroinflammation, oxidative stress, and tau misfolding—that drive progressive neurodegeneration even after active exposure to head trauma ceases.

Research by Steve Cole shows that social disconnection and loneliness activate a pattern of gene expression that drives inflammation.

"I talk about this guy Steve Cole, who's come up with this whole science of how disconnection and loneliness actually activates a whole gene expression pattern that drives inflammation." (said at 1:05:45)

Research led by Steve W. Cole and colleagues in social genomics established that chronic perceived social isolation (loneliness) and social disconnection are associated with a distinct leukocyte gene expression profile known as the Conserved Transcriptional Response to Adversity (CTRA). This pattern is characterized by increased expression of pro-inflammatory genes (mediated by NF-κB/Rel transcription factor signaling) and down-regulation of antiviral (Type I interferon) and antibody-related genes across both human observational cohorts and primate experimental models.
