THE VERDICTS AND WHERE THEY COME FROM

SOLID - The 2020 Nature paper regrew severed optic nerves in mice.
Lu Y. et al., "Reprogramming to recover youthful epigenetic information and restore vision," Nature, December 2020. OSK delivered by AAV into retinal ganglion cells. Demonstrated in mice, not humans.

SOLID - Five habits are worth roughly fifteen years.
Li Y., Hu F.B., et al., Circulation, July 2018. 78,865 women and 44,354 men; gain at age 50 of 12-14 years.

FALSE - ...but they come from the Waldinger study, and one of them is no alcohol.
The fifteen years comes from the Circulation paper, not from Waldinger. That paper's alcohol factor is MODERATE drinking, not abstention.

NEEDS CONTEXT - The Waldinger study ran 40 years on World War II vets.
The Harvard Study of Adult Development began in 1938 and has run 85+ years. Waldinger is its fourth director. Two cohorts: Harvard undergraduates and inner-city Boston boys. Its headline finding - relationships - is his.

NEEDS CONTEXT - The Israeli hyperbaric trial reversed aging.
Hachmo et al., Aging (Albany NY), 2020. 35 participants, NO control group, and the outcome measured was telomere length in isolated blood cells - a surrogate marker, not a health outcome. From the paper's own competing interests statement: "AH, BY, ZY work for AVIV Scientific LTD. ES is a shareholder at AVIV Scientific LTD."

FALSE - You can get away with very little sleep if it is deep sleep.
Kwok et al., JAHA 2018 - 74 cohorts, 3.3 million participants; mortality and cardiovascular risk rise as sleep falls below 7 hours. The glymphatic mechanism he calls settled is contested: Xie/Nedergaard, Science 2013 found clearance rises during sleep; Miao, Franks and Wisden, Nature Neuroscience, June 2024 found it falls.

SOLID - Vascular dementia is the second leading cause of dementia.
15-20% of diagnosed cases. Cleveland Clinic; Alzheimers.gov / NIH.

FALSE - ...and it is the easiest to reverse.
Vascular dementia involves infarction - brain tissue that has already died. No intervention reverses it. The RISK FACTORS are modifiable; the damage is not. Vascular dementia review, PMC 2025.

NEEDS CONTEXT - Bezos, Altman and Armstrong started rival companies, all with billions.
Altos Labs (Bezos) launched January 2022 with $3B. NewLimit (Armstrong) has raised roughly $755M. Retro Biosciences (Altman) operates with $180M. He also called it "Altos Pharma."

NEEDS CONTEXT - 150,000 people die every day of aging.
Andrew Steele, "Deaths caused by ageing," 2026: 105,900 of about 150,800 daily deaths worldwide are attributable to aging - roughly 70%. 150,000 is closer to the all-causes total.

SOLID - The DRD4 7R document read out on air.
Ding, Moyzis et al., American Journal of Human Genetics, 2004; Goeren, 2014. Roughly 48% across the Americas, about 2% in East Asia. We check the document, not the person - it was an AI search result read aloud on the show.

HOW WE SCORE
SOLID - the published record backs it.
NEEDS CONTEXT - true as far as it goes, but the framing is off.
UNSUPPORTED - no evidence either way. This is not an accusation.
FALSE - the published record contradicts it.

Two further claims - US glaucoma prevalence, and whether GLP-1 drugs double the risk of NAION - are held for a follow-up. The NAION literature disagrees with itself across four studies and deserves its own episode.

A NOTE ON HOW THIS IS MADE
The narration voice and most of the imagery in this video are AI-generated. The generated imagery carries mood only - never a citation, date, figure or document. Every fact you read on screen is on a source card built from the literature listed above. We are not doctors and this is not medical advice; we report what the published record says.
