Conviently leaving out that the CIA investigated LSD to brainwash and torture people...>> <<@peterhooper3391 says : Left out of the ‘cities’ discussion is a whole panoply of qualities and aspects of life that make it worth living. Length of life and number of patents is not everything. Maybe it’s time for human beings to stop fearing death and being driven by a fear of death.>> <<@dinhvduc says : This topic on biological scaling laws is absolutely fascinating! The segment explaining why most mammals get "1 billion heartbeats" around [02:00] is mind-blowing and offers a fresh scientific perspective. Connecting biological metabolism directly to urban growth is brilliant storytelling. The research quality and presentation on this channel are always top-tier. I wonder whether people lean towards the 3/4 or 2/3 scaling law as the more accurate model? Huge thanks to the creator—please keep making deeply insightful content like this!>> <<@accognitist says : A human heart beats 72 times a second! So a billion heartbeats should be exhausted by the time they're 32 years of age.>> <<@actiaint says : No the mistake they made was thinking they had the right to put LSD into an animal to start with - cant test humans? well they did - cia even setting up in Germany with ex Nazi scientists to experiment with humans. Leave the animals alone!>> <<@danieloanta1769 says : I encourage everyone to think about that graph. Should we really factor in the average beats a persons heart gets over their life span with something like infant mortality? You wouldn't say the human body has been designed to live for only 40 years if half the population gets killed by falling coconuts! Again, i think we always ignore what is conciously happening with a cell than just randomnimity.>> <<@dave_by_day7632 says : Because large hearts pump more and small hearts pump less>> <<@gilltinder2022 says : These nerds should design a better radiator for my car. lol>> <<@Droid6689 says : Most of this seemed largely unscientific.>> <<@thecarelost6229 says : Who thinks food cooks by weight ? It always cooks by conduction length>> <<@murat_alimkhan says : Yo Derek, u alright? Ur under eye area is not looking good...>> <<@YuxinZhou13 says : 3:11>> <<@jankyso6906 says : Aumulated damage = damage(at time) + scare damage (over time in moment) damage =death cells +rubbish scare damage = I lost my trail. I forgot what I was doing.>> <<@Live_Free_or_d1e says : I think you (probably intentional) left out one of the top three city indicators.>> <<@MarkStover-we3yk says : I read that Neil Armstrong wouldn’t go run on the beach with the other astronauts as he said we only have a train number of beats in our hearts so why waste them running. Seems he was partially right.>> <<@Lickicker says : Funnily enough, if you double the weight of a person, their life is also multiplied by a quarter, its just a negative quarter not a positive>> <<@poporbit2432 says : The average human lives more than 70 years which requires 2.2 billion beats at 60/min. So the 1 billion rule is not accurate>> <<@BryanBrookesSmith says : No one thought to start from an obviously safe amount, and then repeat the experiment after a period gradually upping the amount to see the effects that way.>> <<@Wee_Thought says : Im so glad I have the lifespan of a small whale. How lovely>> <<@Tim_Russert says : 21:59 Derivation of heartbeat invariant>> <<@Tim_Russert says : 21:12 Slight-of-hand used to relate all this to lifespan (Lifespan in captivity vs in the wild not distinguished until 23:13)>> <<@abnteamfruit2152 says : 3:35 excuse me, but am I the only one who hears Ice king from Adventure time here?? He sounds spot on! And he's a scientist!! I think this guy will find a golden crown in the future... just a wild guess yk...>> <<@adrienlorge5362 says : Cities looks like big animals.>> <<@A1i1988 says : but why do we associate longer age per lifetime beats to city size? could that be just correlation bias? why not correlate it to some metric on the advancement of medicine? or other metrics at all?>> <<@A1i1988 says : it's so dumb to kill an elephant by dosing it 1000x before dosing it 1x 😢. it's such a naive narrow minded selfish assumption. Inexcusable.>> <<@Shubhranshu-x6h says : Does that mean if a person reaches the heart limit by doing cardio and exercises in around 10 or 20 years will he/she will die sooner? Please answer.>> <<@Leblackstone says : Evolution is a ridiculously incredible mathematician and physicist and designer. Etc.>> <<@slidekick1004 says : 4:30 these hypotheticals are getting super outlandish>> <<@MichaelRhizal-q9n says : Milligram i think you mean micrograms>> <<@prakharagrawal7318 says : Best video to actually learn>> <<@GlennAbate says : That’s BS because every individual doesn’t live the same number of years>> <<@XDWX says : So is it bad to exercise now since it increases your heart rate?>> <<@xXRacer9000Xx says : Why does every mammal get 1 billion heartbeats in their life?>> <<@Swegma says : So it means someone sedentary would live longer than someone training everyday ? Makes no sense>> <<@ms9001 says : nah they are both wrong. it's actually scaled with 7/10, the middle of 2/3 and 3/4.>> <<@brandonshaffer91 says : a billion seconds is not even 32 years. Most people don't have an average lifetime HR of 60 beats per second. Therefore many humans get at least 3 billion heartbeats... That's a big difference from the video's stated title number.>> <<@thelingla says : Tusco did not die from the LSD. It died from the anti seizure medication the researchers administered it. It is nearly impossible for a living organism to die from LSD.>> <<@vladimirslavik5230 says : Imagine if elefants could have 3B heartbeats in their lifetime. They could live 190 years :)>> <<@GMoney-h3m says : Goyslop>> <<@avijeetpaul9895 says : Very interesting video, never thought that life can be summed up so beautifully with number yet not be bound by numbers>> <<@francoscoc says : Great video making a very abstract concept interesting! But why is there some kid randomly popping in to narrate? Kinda makes the video feel cheesy cause he doesnt convince me that he even knows what hes talking about>> <<@AbdulrahmanAlWahaibi says : سبحان الله>> <<@aurora-cub says : “you need less gas stations per area in a city” and yet a city has 3 gas stations per block and a town has one. just because you can find a mathematical backing for cities being more efficient doesn’t mean that they are. you are ignoring the reality, which is that cities have way more competition in every aspect, so we don’t have so many benefits of sharing resources. just more job opportunities and more unemployment simultaneously, and yes of course they have more pollution. this channel used to be a good watch, but now it just takes interesting concepts and uses them to promote misunderstanding and manipulation. i’m done with it.>> <<@gregrich91 says : 1,000,000,000/80bpm/60min per hour/24 hours per day/365 days per year= 23.78 years I'm 35 so I should have died 11 years ago>> <<@benkamphaus says : BATS! 20% of mammalian species and a huge metabolic rate vs. lifespan outlier and not given their due here.>>
