“New Scientist article. 02:06:10 - Some people, like Tom Cruise and Keanu Reeves, seem to defy aging. 02:08:15 - One 12-ounce can of sugar-sweetened soft drink per day shortened telomere length, corresponding to 4.6 years of biological aging.”

“Some of the factors contributing to these variable phenotypes include persistent damage to our DNA and mitochondrial dysfunction, driven by an altered NAD:NADH ratio, the latter of which has recently been shown to be improved by certain dietary supplements like nicotinamide riboside.”

“The clip also raises questions about micronutrient status. A systematic review found a slight association between vitamin D status and total testosterone, with substantial heterogeneity, and concluded that both may reflect overall health status.”

“Bottled water can contain very small plastic particles. Using stimulated Raman scattering microscopy, researchers identified roughly 240,000 detectable plastic particles per liter on average across three popular bottled-water brands, most of them nanoplastics.”

“A later Framingham analysis followed 2,240 adults for 11 years and found that a red-cell fatty acid model including the Omega-3 Index predicted all-cause mortality about as well as a model using several standard cardiovascular risk factors.”

“If your magnesium levels are inadequate, then your ability to boost mitochondrial number during HIT will be dampened, thus, compromising performance and the mitochondrial mass you would have otherwise gained as a consequence of your hard work and effort.”

“A meta-analysis of resistance-training trials found that protein supplementation produced modest additional gains in strength and fat-free mass, with average fat-free-mass benefit plateauing near 1.62 g/kg/day. This is a group estimate, not a precise requirement for every older adult.”

“In a small immobilization trial, five grams per day of omega-3 fatty acids reduced the loss of muscle volume in young women compared with sunflower oil, supporting continued research on omega-3s and disuse atrophy. Heat is the fourth proposed tool.”

“Dr. Patrick therefore favors lower-risk tools for focus, including high-quality sleep, exercise, cocoa flavanols, deliberate cold exposure, and modest caffeine, before considering an addictive stimulant. Nicotine is not equivalent to tobacco smoke, but that does not make chronic use benign.”

“It remains unknown whether these levels are sufficient for optimal immunological functioning. A large meta-analysis of 32 studies, spanning nearly 50 years, suggests that 25-hydroxyvitamin D levels below 30 ng/mL are associated with a higher risk of death from all causes.”
