Global total sleep time has decreased by approximately 60 minutes over the last 60 years.
"we have seen a 60-minute drop in total sleep time over the last 60 years." (said at 0:22:15)
A systematic review investigating secular trends in adult sleep duration from the 1960s to the 2000s across 15 countries found no evidence of a consistent global decline in sleep duration, let alone a 60-minute drop. Across the countries studied, average self-reported sleep duration increased in seven countries (by 0.1 to 1.7 minutes per night each year), decreased in six countries (by 0.1 to 0.6 minutes per night each year), and showed inconsistent trends in others.

"The 12 studies described data from 15 countries from the 1960s until the 2000s. Self-reported average sleep duration of adults had increased in 7 countries: Bulgaria, Poland, Canada, France, Britain, Korea and the Netherlands (range: 0.1-1.7 min per night each year) and had decreased in 6 countries: Japan, Russia, Finland, Germany, Belgium and Austria (range: 0.1-0.6 min per night each year). Inconsistent results were found for the United States and Sweden. There has not been a consistent decrease in the self-reported sleep duration of adults from the 1960s to 2000s."

Mitochondria are the mandatory endpoint of all aerobic exercise and the site of ATP generation when oxygen is used as a byproduct to make fuel.
"It is the end path of all aerobic exercise. So, in other words, anytime you're using oxygen as a byproduct to make fuel, mitochondria have to be there." (said at 1:18:45)
The speaker's statement bundles two assertions. The first assertion—that mitochondria are essential for aerobic metabolism and the generation of ATP during aerobic exercise—is biologically well established. However, the speaker's second assertion states that oxygen is used 'as a byproduct to make fuel.' In aerobic cellular respiration and oxidative phosphorylation, molecular oxygen ($O_2$) is a required reactant and the terminal electron acceptor in the electron transport chain, not a byproduct. The byproducts of aerobic respiration are water ($H_2O$) and carbon dioxide ($CO_2$). Because the biochemical relationship is stated backwards regarding oxygen's role, the exact claim is contradicted.
A person's limb with greater gross force or strength is typically not the limb used for fine motor neural control.
"typically your force dependent limb is not your neural control limb. So you write right-handed because you have to have fine motor control. Gross strength can be in the opposite side." (said at 1:32:41)
The claim that a person's force-dependent limb (gross strength) is typically not the limb used for fine motor neural control (the dominant limb) is contradicted by human motor control and normative anthropometric data. In general populations, the dominant hand—which is preferred for fine motor tasks like writing and skilled manipulation—is typically approximately 5% to 10% stronger in gross force (such as grip strength) than the non-dominant hand, particularly in right-handed individuals. While motor control theories (such as dynamic dominance) indicate that the non-dominant limb is specialized for impedance/postural control and the dominant limb for trajectory and intersegmental dynamics, gross maximal strength is typically greater in, or roughly symmetrical with, the dominant limb, rather than residing on the opposite side.
