Building a Better Future through Regular Exercise | Aleksandar Marchev | TEDxYouth@SWA
## Speaker Context * Speaker identity: Alex, a business management and INS teacher. * Audience, setting, occasion of the talk: Ladies and gentlemen; implied academic/public speaking setting. * Framing: The topic has tremendous implications for the future and for the future of humanity. ## People * Alex: Speaker; business management and INS teacher at SWA middle school high school for eight years. * Socrates: Ancient figure, quoted regarding the importance of physical limits and capabilities. * John Loach: Figure quoted regarding the "sound mind in a sound body" state of happiness. * Father: Speaker's father; passed away at age 80 after a stroke, spending nine months in bed. * Individual (Example): A highly trained individual (gymnast) who was reasonably fit when a teenager, didn't exercise for about 20 years, regained 33 pull-ups at age 40, continued exercising, and was still able to crank out 20 pull-ups at age 74. * Children/Teenagers: Group seen at a water station during the race who gave water to the speaker. ## Organizations * UN (United Nations): Source stating that the number of people above 65 will double in the next 25 years. * Stanford University: Source that conducted the survey on step counts in Indonesia. ## Places * Developed countries: Location where life expectancy is currently about 80 to 85 years. * modern day Ethiopia: Location where the reconstruction of a man lived 160,000 years ago. * Indonesia: Location cited with an average step count of less than 4,000 (3,500). * Lombok: Location of Ringani Mountain, where the speaker participated in the Rejani 100 race. * Bali: Location from which the speaker could see Ringani Mountain from the shore. ## Tools, Tech & Products * Instagram: Platform mentioned where people might post pictures. * Straa: Platform mentioned for showing off fitness achievements. * Phone: Device whose battery ran out during the race. ## Concepts & Definitions * Availability: Concept described as the most important thing, being physically able to show up. * Compound: Concept from business management used to describe the benefits of regular exercise. * Risk management: Concept from business management applied to managing health risks. * Biological age: Concept describing physical state that is as fit as teenagers, achieved through consistent and regular exercise. * V2 max: Measurement used in the survey, which is a measure of cardiorespiratory fitness. * Diseases of abundance: Category of diseases (e.g., diabetes, cardiovascular disease) that exercise can prevent or slow down. ## Numbers & Data * Eight years: Duration Alex has been teaching at SWA middle school high school. * 160,000 years: Time period that the man in the reconstruction lived. * 15 to 20,000: Average steps per day taken by people in the past. * 5,000: Guest guess for average step count in Indonesia today. * Less than 4,000 / 3,500: Actual average step count in Indonesia according to Stanford University. * 80 to 85 years: Current life expectancy in developed countries. * 25 years: Time frame within which the number of people aged 65 and over will double. * Last 6 to 10 years: Period of life spent in a disabled state for adults in developed countries. * 80 years: Age of the speaker's father when he passed away. * Nine months: Duration the speaker's father spent in bed after his stroke. * 33 pull-ups: Record regained by the highly trained individual at age 40. * 46: Age when the individual continued exercising. * 74: Age when the individual was still able to crank out 20 pull-ups. * 5 to 10: Estimated number of healthy years added to lifespan by exercise. * 54%: Decrease in the chance of hospitalization due to fitness during the pandemic. * 31%: Decrease in all cause mortality for reasonably fit individuals. * 120 thousand: Number of participants in the survey analyzed. * Four: Number of different cohorts in the survey (out of shape, reasonably fit, fit, athletes). * 3,700 meters: Elevation reached during the climb to the top of Ringani Mountain. * 100 kilometers: Total distance run in the Rejani 100 race. * 53: Distance completed by the speaker in the Rejani 100 race. * More than 20 hours: Duration the speaker went without sleep during the race. ## Claims & Theses * The knowledge about the benefits of exercise is nothing new. * The best ability that we have is availability. * If you are not physically able to show up, share your experience, you would have no impact. * The life expectancy of the average human has increased exponentially. * Are we going to live healthier? (Question posed) * Adults aging adults spend the last 6 to 10 years of their lives in a state which we call disabled. * There is something more that could have been done to give us those nine months but in a better state in a state where we could communicate where he would suffer less. * Regular exercise consistently is absolutely fundamental for us to engage in. * On average, people took between 15 and 20,000 steps per day in the past. * Walking is one of our superpowers and it's greatly undervalued. * Engaging in regular exercise benefits are disproportionate to the amount of time and effort that you will put in. * Health is the greatest assets that we can have. * Reasonably fit individuals have a very substantial decrease in all kinds of diseases and factors that affect our health. * If you are reasonably fit, you decrease your chance of dying of any cause in the next year by 31%. * Exercise can make those last decades of our lives when we're most susceptible to disease productive, healthy, and meaningful. * Exercise is the single most powerful intervention that we can do for our health. * For every hour of exercise, you're gaining three extra hours (1 to 3 ratio). * We are not exercising for a result; we are exercising for life. ## Mechanisms & Processes * How to be physically fit for future knowledge transfer: Staying physically healthy and able to perform. * Process of physical decline: Transitioning from periods of capability to spending the last 6 to 10 years disabled. * Process of step counting: Tracking daily steps to slowly increase physical activity. * Cardiorespiratory fitness measurement: Using V2 max to measure fitness levels across cohorts. * Training effect: Consistency in exercise leads to biological age advancing past chronological age (e.g., 50-year-old athletes as fit as teenagers). * Injury mitigation: The suggestion that if one doesn't have time to warm up, warming up and calling it a day is better than pushing too hard and being sidelined. ## Timeline & Events * 160,000 years ago: Time when the modern day Ethiopia man lived. * Today: Current time reference point. * During the pandemic: Time when the speaker started running regularly. * Survey timeframe: Study covered participants who were considered out of shape, reasonably fit, fit, and athletes. * Last decade of life: Period to consider for desired activities (5-10 activities). * Rejani 100 race: Event the speaker participated in. * Night of the race: Time when the speaker reached the point where he was hallucinating and out of water. ## Examples & Cases * Socrates Quote: "it's a shame to grow old without being able to see what you're capable of and testing your limits." * John Loach Quote: "the mantra of sound mind in a sound body no is a short description of the happiness state in this world." * Personal experience (Father): Father passed away at 80 after a stroke and spent the last nine months in bed. * Historical Man Reconstruction: Man from modern day Ethiopia, 160,000 years ago, who lived by necessity of survival. * Indonesian Step Count: Average step count in Indonesia is less than 4,000 (3,500) according to Stanford University survey. * Gymnast Example: Individual regained 33 pull-ups at age 40 and was still able to do 20 pull-ups at age 74. * Speaker's Race Experience: Completed 53 out of 100 kilometers in the Rejani 100 race, experiencing extreme exhaustion but fulfillment. * Water Station Encounter: At a water station during the race, a group of camping teenagers gave the speaker water when he was out of it and hadn't slept for more than 20 hours. ## Trade-offs & Alternatives * Living longer vs. Living healthier: The core question regarding advancements in medicine. * Staying highly fit (athletic level) vs. Being reasonably fit: The progression shown in the fitness chart. * Doing hard exercise (Risk) vs. Not exercising (Cost): The trade-off regarding the necessity of movement for basic life function. * Pushing too hard and injuring oneself vs. Warming up and calling it a day: The suggestion for managing over-excitement about exercise. ## Counterarguments & Caveats * The ancient knowledge of exercise benefits is not new (Counter to assumption that current knowledge is novel). * The life expectancy increase is good, but quantity vs. quality is the issue (Caveat on longevity). * The diagram of aging shows spending 6 to 10 years disabled (Caveat on current reality). * The individual’s 33 pull-ups example: Speaker warns that he is not telling the audience to do pull-ups because there are probably better exercises that fit them more. * Not being an extreme athlete: The benefit calculation (31% decrease in mortality) is specifically for reasonably fit individuals, not extreme athletes. * Expense of exercise: Acknowledged that gym memberships, coaches, etc., can be expensive, but alternatives exist. * Time commitment: Acknowledged that exercise can take time, but reframing it as an investment. * Over-excitement about exercise: Warning against forgetting to pace oneself, leading to injury. ## Methodology * Survey analysis: Using data from 120 thousand participants divided into four cohorts (out of shape, reasonably fit, fit, athletes) to track cardiorespiratory fitness (V2 max). * Comparison: Contrasting the seditary curve with the trained curve to estimate lifespan gains. ## References Cited * Socrates (Quote). * John Loach (Quote). * UN: Source for doubling population aged 65+ in the next 25 years. * Stanford University: Source for the survey on Indonesian step counts. * The data behind the fitness chart: (Unnamed source, but relates to cohort survey). ## Conclusions & Recommendations * Focus should be on understanding *why* exercise is fundamental, not just stating the fact. * Track step counts and try to slowly increase them. * The motivation for exercise should be "for life," like being there for a child's wedding or picking up a grandchild. * The goal is to move from the seditary curve to the trained curve of an individual. * Stay consistent in your pursuit, to play the game and to stay in the game, to manage your expectations and to have a very strong why. * The ultimate goal for humanity is to leave a legacy to our children, leading by example. ## Implications & Consequences * If humanity does not prioritize fitness, the gains from longevity will be negated by periods of disability. * If the speaker's advice is followed, lifestyle changes can add between 5 and 10 healthy years to lifespan. * If we don't build this legacy, we jeopardize the future health of humanity. ## Open Questions * What is the best exercise routine for an individual, given the variety of body types and needs? (Implied by the warning about pull-ups). * How can we better integrate exercise into daily life to prevent periods of inactivity? ## Verbatim Moments * "it's a shame to grow old without being able to see what you're capable of and testing your limits." * "the mantra of sound mind in a sound body no is a short description of the happiness state in this world" * "the best ability that we have is availability" * "quantity versus quality" * "the last 6 to 10 years of their lives in a state which we call disabled." * "The best ability that we have is availability" * "our superpower and it's greatly undervalued." * "We are exercising for life. That should be the reason and your motivation." * "I'd like to be able to travel independently, go up and downstairs." * "The risk to reward from exercise is beyond comparison." * "If we want to truly advance humanity, we must leave this legacy to our children, lead by example, and make sure they follow in our footsteps."
