How Mouth-Breathing Changes Face Shape (0s)

Mouth-breathing in children can lead to unattractive alterations in facial structure, as opposed to nasal breathing which does not.
Chewing hard foods is essential for the development of the mouth, face, and teeth and can affect overall health, such as cardiovascular and metabolic health.
High usage of orthodontic procedures such as braces and retainers may be due to poor breathing practices and excessive consumption of soft foods.
The Mew method aims to restore normal craniofacial development, and the book "Jaws: The Hidden Epidemic" features impressive before-and-after photos of children who corrected their mouth-breathing habits.
Nasal breathing during rest is beneficial for craniofacial aesthetics and is modifiable throughout life.
The book suggests no need for commercial jaw exercise products; instead, emphasizes the benefits of tough food for natural jaw development.
Mouth-breathing can limit oxygen intake, potentially diminishing brain oxygenation and leading to sleep apnea.
Breathing through the nose utilizes the sinuses for better air and fluid movement, and it can help correct deviated septums without the need for surgery; deliberate nasal breathing is advocated.
The nasal microbiome acts as a defense against infections, unlike mouth-breathing, which exposes individuals to higher risks, particularly during wintertime.
Images in the book illustrate notable differences in attractiveness and dental health between twins raised with different dietary habits, emphasizing the impact of diet and breathing on development.
The facial changes associated with excessive mouth-breathing include the recessed chin and protrusion of the face, along with droopy eyes due to the underuse of sinuses near the eyes; these changes are reversible with proper habits.
Proper chewing techniques and nasal breathing habits are encouraged, also as a way to potentially reduce the intake of low-nutrient density calories; adults are also encouraged to consume more solid foods rather than relying on softer, processed foods or calorie-rich drinks.

What We Misunderstand About Stress (8m16s)

Individuals perceive stress differently based on their mindset or belief system.
Voluntary exercise in animals leads to health improvements while forced exercise does not.
Mindset about stress changes its impact on health. Consideration of stress as useful can enhance focus and memory.
Viewing stressful events, like the Boston Marathon bombing, can elicit greater stress responses in viewers than in those who experienced the event firsthand.
Beliefs about willpower, whether it’s seen as a limited or unlimited resource, affect its actual utility in tasks.

On Tenacity, Willpower, and Motivation [N/A]

Tenacity and willpower are not the same as motivation, but they are interrelated.
The anterior midcingulate cortex (aMCC) is a brain area associated with the perception of challenges and the generation of tenacity and willpower.
Size and activity in the aMCC increase with successful resistance to temptation or dieting, and failing dieters show no increase or a decrease in these measures.
Superagers have larger aMCC sizes, maintaining cognitive function as they age, while typical aging involves a reduction in this area.
Engaging in difficult tasks, especially those one dislikes, activates and potentially increases the size of the aMCC.
The experience of 'micro sucks' or 'macro sucks'—tasks or challenges that are unpleasant but manageable—can enhance willpower and tenacity.
It is beneficial to occasionally push oneself past the point of task completion to further increase willpower.

Understanding and Harnessing Stress for Health [N/A]

Perception of stress as harmful can lead to negative health consequences, while viewing it as beneficial can improve performance.
Beliefs about willpower influence its application, suggesting that viewing willpower as non-depletable leads to better performance in consecutive tasks.
The aMCC plays a critical role in willpower and tenacity, which can be harnessed through challenging tasks and by pushing beyond comfort zones.

Practical Takeaways for Enhancing Tenacity and Willpower [N/A]

The aMCC is a target for enhancing willpower and tenacity, which can be achieved by voluntarily engaging in challenging activities.
It's important to incorporate 'micro sucks' or small challenging tasks into daily routines to boost the size and activity of the aMCC.
Overcoming discomfort in tasks, rather than just engaging in challenging but enjoyable exercises, enhances willpower according to the research.
Pushing just beyond satisfaction in tasks can provide an extra boost in activation of the aMCC.

On the Role of Deadlines and Discomfort [N/A]

Deadlines can be a powerful motivator and stressor that drive task completion and active engagement.
For some, procrastination serves as a way to create self-imposed pressure and deadlines.
Deliberately choosing to engage in slightly more difficult tasks than necessary can enhance the aMCC and improve willpower.

Ambitions for Wellness and Training [N/A]

Engaging with a comprehensive health and blood panel service like Marrick Health can provide insights into one's physical health and optimize wellness strategies.
Personalized recommendations can be given based on extensive blood work, impacting aspects such as testosterone levels and overall health.

People Are Recognizing the Need to Focus on Health & Fitness (24m56s)

There is a growing awareness among performers outside of traditional physical conditioning that health and fitness are crucial for optimal performance.
It's acknowledged that taking care of the body improves the mind, and vice versa.
Recommendations include 150 to 200 minutes of moderate exercise (Zone 2) weekly and high-intensity sprint-type workouts to increase maximum heart rate once a week.
Resistance training should be done for each muscle group at least six times a week, not necessarily to failure but with substantial effort.
There has been a misconception, especially among women, that weightlifting leads to excessive bulkiness, but this is a myth as gaining significant muscle mass is challenging even with concerted effort.
Resistance training is linked to cognitive function and preservation of neuromuscular function into old age.
It's advised that engaging in activities one dislikes—such as resistance training for some—may present the most significant opportunity for improvement and brain stimulation.
Resistance training offers a unique incentive by showing a glimpse of potential progress through muscular "pump," which indicates the achievable hypertrophy after consistent effort and recovery.
Even if exercise is not enjoyable for someone, it's beneficial for cognitive function and overall health and should be pursued.

How the Mind Improves When the Body Improves (31m43s)

Increased blood flow to the brain enhances cognitive function, as the brain is highly metabolically demanding.
Blood flow is crucial for cognitive function, and restricted flow impairs it.
Physical exercise, particularly cardio and resistance training, improves blood flow, reduces inflammation, and boosts brain health.
Age-related cognitive decline and dementia are sometimes linked to metabolic issues, akin to "type 3 diabetes," leading some to follow ketogenic diets.
Loadbearing cardiovascular exercise releases osteocalcin from bones that supports nerve health and function in the hippocampus, vital for memory formation.
Experiments indicate blood from exercised animals, when transferred to aged or cognitively impaired animals, improves cognitive function, suggesting exercise creates beneficial bloodborne factors.
Comedy and tasks requiring cognitive dexterity benefit from the enhanced brain function due to exercise.
Cognitive maintenance and improvement require a combination of activities, including cardiovascular training, resistance exercises, social engagement, and intellectual pursuits such as crossword puzzles.
Superagers actively engage in challenging activities and pressure themselves, which helps prevent brain structure shrinkage with aging.
No pill or injection can replace the benefits of learning and effort for brain health; genuine effort is necessary.
A balanced combination of resistance training and cardiovascular exercise is pivotal for overall health, including cognitive functioning.
Exercising individuals seem to have better cognitive function compared to those only specializing in one type of exercise.

Are Phones Ruining Our Focus? (1h33m23s)

Technology, particularly the constant shifting of focus on phones and social media, undermines the brain's ability to maintain prolonged focus.
Repetitive focus-shifting on devices can be compared to detrimental physical habits which can impact the benefits of cardiovascular exercise, although movement throughout the day remains beneficial.
The act of scrolling on social media simulates placing oneself in rapidly changing contexts, requiring constant mental adjustment and undermining focus-related brain circuitry.
This constant context switching is in stark contrast to the more goal-directed focus of real-world interactions.
The human brain is adaptable and creates new mental 'maps' or modules for frequent experiences, including digital engagement such as swiping on phones.
Children developing in the digital age are creating brain maps for swiping and using thumbs for communication (texting) at the expense of other potential functions as the brain adapts to these habits.
Widespread concerns arise regarding the long-term effects of phone use, drawing parallels to the initial ignorance of the detrimental effects of smoking.

Why Phone Use Isn’t an Addiction (1h47m49s)

Phone use is often mislabeled as an addiction; it's more akin to a compulsion.
A compulsion is a behavior that usually intensifies obsession rather than relieves it.
The action of scrolling on a phone often increases the 'itch' rather than satisfying it.
The speaker acknowledges that phone use can be for practical tasks, such as information gathering, but it can also be aimless.
Attempts to change one’s social media algorithm to improve content intake can be slow.
Even uninteresting content can provoke curiosity and lead to excessive time spent on unproductive activities.
The incentive to use social media is sometimes provided by occasional worthwhile discoveries.
Social media can have positive aspects, like learning new things and connecting with old friends.
Self-discipline is considered crucial to navigate current media environments effectively.

Importance of Mental Stillness and Active Thinking (1h47m49s)

Influential individuals often engage in periods of inactivity paired with active mental engagement.
These practices include deliberate stillness while allowing the mind to engage in complete thoughts or creative ideas.
The unconscious mind may offer a more significant contribution to thought processes during these times, leading to novel ideas.

The Science Behind Procrastination (2h15m4s)

Procrastination is linked to creativity, with procrastinators accessing creative states that non-procrastinators may not.
The origins of procrastination are complex and not tied to one specific cause.
Overcoming procrastination involves doing something more challenging than the task being avoided for a short period, leveraging the dopamine reward system.
As an example, a person avoiding writing could engage in a more disliked task, like working with spreadsheets for five to ten minutes.
Understanding the dynamic hierarchy or "Dynamic subordination" of tasks can help prioritize and tackle what needs to be done.
Deliberate cold exposure is mentioned as a potent method for overcoming procrastination due to its immediate stressor effect and the significant challenge it imposes on one's willpower.
Utilizing deliberate cold exposure requires overcoming a substantial mental barrier which can make other tasks seem less daunting by comparison.
Alongside cold exposure, having hard conversations or confronting other unpleasant tasks can serve as a deterrent to procrastination.
