The Environmental Working Group has reported that over 122 million Americans drink tap water containing high levels of chemicals known to cause cancer.
"The Environmental Working Group has also shown that over 122 million Americans drink tap water with high levels of chemicals known to cause cancer." (said at 1:02:54)
The Environmental Working Group (EWG) has published multiple reports and peer-reviewed risk analyses (e.g., using their Tap Water Database and UCMR datasets) modeling cumulative cancer risks for tens to hundreds of millions of Americans exposed to trace contaminants like disinfection byproducts, arsenic, nitrates, and PFAS. However, describing these as 'high levels' is an overstatement. The vast majority of municipal tap water in the United States complies with federal Maximum Contaminant Levels (MCLs) established under the Safe Drinking Water Act. EWG calculates risk exceeding thresholds based on its own non-enforceable 'health guidelines' (often modeled on a 1-in-1,000,000 lifetime excess cancer risk), which are orders of magnitude lower than federal regulatory standards, not concentrations typically characterized toxicologically as 'high'.
Ninety percent of adults in the world consume caffeine daily.
"90% of adults in the world drink caffeine every day." (said at 1:34:45)
While caffeine is recognized as the most widely consumed psychoactive substance globally, epidemiological surveys and reviews estimate that approximately 80% of the global population consumes caffeine daily. Figures of 85% to 90% daily consumption specifically describe adults in North America and the United States rather than the worldwide adult population.
A resistance training session lasting 30 to 60 minutes triples or quadruples circulating cortisol levels.
"As you and I both know, a good solid resistance training session of about, you know, 30 minutes to an hour will triple or quadruple circulating cortisol levels." (said at 1:53:20)
While acute resistance training can stimulate the hypothalamic-pituitary-adrenal axis and increase circulating cortisol concentrations, claiming that a typical 30- to 60-minute session routinely triples or quadruples (3- to 4-fold increase) cortisol levels is an overstatement. The magnitude of acute cortisol elevation depends heavily on exercise volume, intensity, muscle mass involved, and rest intervals. Moderate to high volume protocols with short rest intervals typically produce modest to moderate transient increases (e.g., 20% to ~100% above baseline), and standard resistance exercise often fails to elicit significant cortisol elevations or produces responses well below a 3- to 4-fold surge unless extreme, high-stress exhaustion protocols are used.

"Protocols high in volume, moderate to high in intensity, using short rest intervals and stressing a large muscle mass, tend to produce the greatest acute hormonal elevations (e.g. testosterone, GH and the catabolic hormone cortisol) compared with low-volume, high-intensity protocols using long rest intervals."
