“In the five-year Generation 100 trial, adults ages 70 to 77 completed supervised high-intensity interval training or moderate continuous training, demonstrating that structured vigorous exercise can be feasible in older populations when it is introduced progressively and matched to health and fitness.”

“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”

“Elevated biomarkers of inflammation, which are commonly observed in people who have depression, chronically activate the body's inflammatory response system, promoting the development of depressive symptoms and inducing changes in brain and neuroendocrine function.”

“Insulin-like growth factor 1 (IGF-1) plays a role during childhood for growth and continues later in life to have anabolic and neurotrophic effects. IGF-1 is also implicated in contributing to aging and enhancing the growth of cancer after it has been initiated.”

Many of the anabolic effects of growth hormone are thought to be mediated by insulin-like growth factor-1, or IGF-1 (https://www.ncbi.nlm.nih.gov/pubmed/18500379), which is synthesized primarily in the liver but also in skeletal muscle in response to growth hormone.

“Study. 01:43:00 - High animal protein intake was only positively associated with cardiovascular mortality among individuals with at least one unhealthy lifestyle risk factor, such as obesity or sedentary lifestyle. Study.”

“01:52:55 - Environmental enrichment creates epigenetic changes that benefit learning and memory in rodents and these benefits transfer to offspring. Study. 02:05:00 - NASA study showed that gravity influenced expression of genes involved in metastasis.”

“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.”
