Vigorous aerobic physical exercise is the most empirically well-validated strategy for increasing neuroplasticity.

"And so exercise, physical exercise, particularly vigorous aerobic exercise of the sort that you're describing is indeed, as you are hinting, the most empirically well-validated strategy for increasing neuroplasticity." (said at 0:02:32)

Substantial evidence from systematic reviews and randomized trials confirms that physical exercise—particularly moderate-to-vigorous aerobic exercise—robustly promotes neuroplasticity, as demonstrated by increases in circulating neurotrophins (such as brain-derived neurotrophic factor, BDNF), enhanced motor cortex excitability, and structural/functional brain adaptations. However, designating vigorous aerobic exercise as definitively 'the most empirically well-validated' strategy requires context: human evidence largely relies on surrogate biomarkers (e.g., peripheral BDNF, transcranial magnetic stimulation measures) rather than direct cellular synaptic measurements, and other modalities (such as resistance training, combined training, and cognitive training) also demonstrate comparable empirical support for promoting neuroplasticity.

People with stronger social connections have approximately a 50% lower likelihood of mortality compared to those with fewer social connections.

"I remember reading this study—I mean, it's been years, but I think it was out of Brigham Young perhaps—showing that social connection, you know, people with more social connection ... were like 50% less likely to die than people that didn't have as much social connection." (said at 1:18:48)

The speaker is referencing a landmark 2010 meta-analysis led by researchers at Brigham Young University (Holt-Lunstad et al.), which synthesized 148 prospective studies comprising 308,849 participants followed for an average of 7.5 years. The meta-analysis found an odds ratio of 1.50 (95% CI, 1.42 to 1.59), representing a 50% increased likelihood of survival for individuals with stronger social relationships compared to those with weaker relationships. While colloquially cited as a '50% reduction in mortality risk' or '50% less likely to die', an odds ratio of 1.50 for survival is mathematically distinct from a 50% decrease in mortality rate, although the protective association is robust and comparable in magnitude to well-established lifestyle risk factors.
