If the schools taught chemistry like this, more kids would find it interesting and worthwhile...
Be careful, education reform might one day lead to a well informed electorate.
Good thing I’m a kid at school:)
STEM subjects are definitely a lot more interesting as a kid when it's applied to something practical.
fyi, they do teach this in schools (at least in australia)
Source: am in year 10 and had more or less knew everything in this video.
But yes, there should be more emphasis placed on more practical skills such as this.
I learnt this is biology...
"So you are breathing it all out"
Me - Looks at my gut... starts breathing fast
Literally the next thing he sais - "You can't just breath faster"
Hahahhaha
😂🤣
😂🤣😂
I was going to just start blowing up a bunch of balloons every day until he said that lol
I was doing it too, until I read your comment. Lol
Wow this was my first time to actually finish a 20 min ted talk. Very interesting! Thanks a lot sir!
Outrageous
Same
im a student going into my las year of high school. if i had seen this in my sophomore year when i took biology, i would have loved the class. the fact that this has millions of views and has been around since i was in 3rd grade, and that i hadn't seen this until now is astonishing. i think i should share this with my old biology teacher.
yes! share it!
Does this skirt make me look C55H104O6?
Vincent Vicari well played..
so if fat is mostly hydrogen, which is lighter than air, why don't we float in air?
Steve Haigh lol

can we get this on a tshirt?
Summary: Eat less, Move more, Keep Breathing.
Is actually that simple.
well eat more (healthy foods), move more, keep breathing is more efficient
Meat only, move and mindfulness works for me
@@jmcglifting453 that's healthy which difference aspect of weight loss
u will lose ur mind and all the muscle/lean mass u have,, eat less but nutrition dense food, so that u lose weight healthily
This kind of lectures can make you fall in love with science I love it 🥺
Chemistry never had been this interesting to me in my entire life.
lol agreed
If you're in ANY allied healthcare degree in college it's - BIOCHEMISTRY!
Knew it turned into co2 and h20 but not the percentages! That’s so cool!
Same for me, he made it fun
Then go and watch breaking bad
That was probably the most direct and straight forward discussion on weight loss I've ever encountered! Bravo!
So sad that is absolutely oversimplified and not really true...
Which part isn't true?
+Dean Graves the part where all the food you eat is use for energy and or stored . A lot of the food you eat is used to repair and replace cells in the body. research done by ali crum proofed that just by modifying what a person believed ,has an effect on weight loss and or metabolic action ... eat less move more fail.
Nico, here's an easier simplification of what he said. If your body can't use everything you've put into it, the excess is stored or excreted. Too much energy in versus energy used = overweight. Thus, move more, eat fewer KJ or calories, make yourself cold while maintaining KJ/calories, etc. It really is that easy. He isn't comparing raw energy intake between individuals (i.e. fast vs slow metabolism); only in a particular case, if weight is a problem, just eat less, or move, or both.
+ualaelinlive I understand what he said ... the problem comes in when you understand that the process the determines energy yield(calories ) of food and what happens to food in your body is vastly different second to that food you eat doesn't only provide energy most of it is used to repair and replace cells in your body. Thirdly ali crum's research strongly suggest that by altering only a set of believes weight loss will occur .
At 4:57 he actually says that little arrow there is a 3 year degree ... No how much would you trust a doctor that's 3 years short on his degree?
Now when you eat your metabolism speeds up and when you don't eat it slows down so you must be referring to basal metabolic rates and that has nothing to do with having a weight problem .
this man inspired and explained chemistry better than all the teachers I've had in elementary, high school, and university put together! God bless your awesome practical soul Ruben Meerman!
It's a very superficial amount of chemistry in the video.
I'm old...we never had chemistry in grade school or middle school & if it was offered in high school....I failed to notice.
Or maybe it was my lack of math skills...only one year required, so it wasn't offered to me 🤔
x2
Physics really.
I 2nd that💪🏽
first seen this nearly 10 years ago...still amazing to watch. he does such an amazing job showing how this works
Exactly
This should be required material for any Personal Trainer. Thanks for the video and the book!

@@deepsinghheadlesswarrior8972 Does adding to the watch later playlist affect the algorithm? I didn't know that.

Amazing explanation. My husband and I just started on our weight loss journey. He wants/needs to drop around 20lbs and I around 10-ish. We bought all the gym equipment needed, bike, treadmill, row, and that new TONAL. I will show him this video to take another step in our journey. Thank you!!
I'll wait too see if achieve your task
It’s a lot easier than people make it sound
@@kpeezy776 you dont need any gym equipment to lose weight. 90% of this is better nutrition. You just need to eat less calories than you burn. Most people fall into the trap of adding exercise, but also consuming more food (because the body has established a "normal" rate of excess calories each day and that's how your appetite works. Your appetite will trick you. It is not telling you what the body needs. It's telling you what you normally do. And since you are looking to make a change (new healthier weight and lifestyle) you have to ignore your appetite and choose a good macro nutrient profile. Adding exercise helps of course, but ultimately you want to eat approx 100-150 calories less than you burn (you BMR + any exercise). Counting calories can be a bit tiring and tricky, but once your body adjusts to being a little hungry, you no longer associate that feeling with hunger, but with wellness, with not consuming excess.
i don't know where your husband and you are in your journey, but if you met your goals, congrats, and if not, here's a friendly reminder to not give up! consistency really is the key
@@the42nd this
Educational, thought provoking and comical. A perfect combination. One of the most engaging presentations I've ever seen.
So I'm breathing in other peoples calories, I knew it wasn't my fault.
And yo corona 😳😳
LMAO 🤣
Lmaoao
Errrr, wrong. Did you not watch the video? It’s not calories you’re breathing in...
😂😂😂
I know where the weight goes. It goes behind the couch, reproduces and then jumps back on me when I least expect it. That is where it goes.
mcconn746 lol
Hahaha
Mc Conn 746: It boomerangs back!
This makes so much sense now hahaha
cool
At 20:46 he should have said "eating low carbohydrate diets" instead of "low protein." He was talking about ketosis which is a result of keeping carbohydrate consumption generally below 20 grams per day to lose weight.
Personal experience, ketosis is very effective as a means of weight loss with my loss from 223 pounds down to 185 pounds.
Ketosis was/is used to heal the brain of epilepsy.
It is a more efficient engergy supply for the brain than carbohydrates, and actually stabilized my moods.
Very impressive. I think now I will be more committed to exercise now that I understand the science behind it. Thanks for this solid explanation, Ruben.
This! This is how teacher need to impart information. With energy, engagement, personal relativity, enthusiasm, excitement, visualisations, humour, and regional colloquialisms (lol, bingo wings. 😂).
As a science lover 🧪 and someone struggling to lose weight I highly enjoyed this lecture.

This was so throughly educating and enjoyable. You definitely break it down into simple terms and make it very easy to understand. I enjoy chemistry and have a good background on it but learned a few things today. Thank you! I did watch a video a few months ago (I don’t recall from where, but they explained where our weight loss actually went. But it was nothing compared to this! This was so educational! And fun. 💯🙌💗
This is one of the best conferences I have seen in a long time. A great presentation!
The title should be: The chemistry of weight loss.
I recommend you try this Weight Loss Green Store Tea product to help you get on that right road to a healthier you!
16:44 no it is math cause he broke it down to percentages:
%84 exhalation(CO2) + %16 water (H2O)
Chemistry is just a subsection of physics and physics is just a subsection of maths

The way we get energy blew my mind a bit. It's all still the sun.
Excellent presenter and educator. Clearly knows his stuff, explains it well, and keeps the audience engaged.
Everything is the sun. Do some more reading on quantum physics and how it plays into biology. We SEE due to photons. We are powered by the sun ,but it's processed by the body. It's where melanin comes into play. Read about how mitochondria in the cells work.
The earth evolved with the sun. All life upon the earth is connected with the sun.
Fittingly, eventually, the sun will go nova and destroy all life on earth.
What it giveth, it will take away.
Except that he clearly doesn't understand ketosis, and there are many other scholars to argue that it's much more than eat less move more 🙄
i've learned more from this than i have in most science classes, all because of this guys personality, it makes you actually want to listen
Wow what an incredible teacher, very informative indeed... message received loud and clear! Thank you
i love how he straight up kept the safety glasses
😂😂😂I didn't notice that until i saw you'r coment,the glasses looks good on him though🤓,love and Light from faraway Norway 🤗
@@sylwia7060 Exactly the same!
"Safety glasses on."
20 minutes of TEDx taught me more than multiple years of school ❤
Condor you were the one child left behind 😆
hahaha
Were you making that face while watching lol
I just had that same thought
You weren't paying attention...
I absolutely loved this talk! Fun, funny, made sense, and motivational! Just awesome
This was superb, so well explained, such a valuable answer, a fun and interesting presentation. I haven't been to school for a long time so loved catching up in this session. I loved Chemistry.
Ruben I'm also a science educator but you do it 1000x better. I loved your simplicity, enthusiasm, energy and charisma. It seems society in general has lost it's faith and trust in science and it makes me sad and worried for the future, like we are fighting a losing battle. If we all had science teachers like you I think the world would be a much better place. Keep up the good work, you have inspired me!!
It's not that people have lost faith in science, it's science that has lost faith in itself. Climate Change research is driving this trend more than anything. It is a pre-determined conclusion to which data and hypotheses are made to fit, because if they don't YOU GET NO GRANT MONEY. There is $0 of funding available from any major source for research that leads to a conclusion contrary to the 'consensus'. This is terrifying. The whole point of the scientific method is that consensus can always be wrong in light of new information and understanding. This has happened on many notable occasions, where the research of one individual rewrote and wiped out the supposed laws of entire fields that had stood as fact for, in some cases, thousands of years. Heliocentrism and Plate Tectonics are two towering examples.
I just worry that 500 years from now, people will read scientific history books and snicker at our time and say "Wow, they believed people could actually affect an entire planetary climactic system, primitive idiots. They probably thought the Earth was flat, too, hahahahahah....oh wait, polls from that time showed the majority of people under 35 DID believe the planet was flat."
Above all, science, more than any discipline, needs to keep an open mind free of presupposition.
Robert Morgan I know we need to start getting that flat Earth funding going , am I right? Moron.
Bobsmithgeorgette, talking about education and the world being a better place, even though I doubt that Donald Trump would understand the mathematics he might enjoy the visual effects and maybe take in a little bit of it. And then he would go and say: 'I told you, global warming is fake news!!'
If you want science teachers like him, PAY THEM BETTER. And give them plenty of administrative support (including getting rid of useless "assessments" of "skills"); replace that edubabble with SUBJECT MATTER.
Robert, the hole world is not like the US, in my country our government pays for a lot of the scientific work, not private companies. We do not need to come up with results showing that "this is not harmfull". Best regards from a swedish scientist. :)
The stated intention of his presentation was not to describe in 20 minutes or less the how or why of obesity, but to deliver a mathematics (84% as CO, 16% H2O) based answer to the question of 'Where does fat go?'. To that end, his speech was enlightening, articulate and entertaining. Excellent presentation.
And then he said that in order to lose weight, you should eat less and move more, which is a useless oversimplification of the task at hand. In other words, it's interesting for the science, but it's useless for weight loss.
Simboiss True
Run. Do push-ups sit ups, subscribe to the bodycoach. There you go. You have to supply discipline
Simboiss Why? It's true, if you take in less calories then you burn you will loose weight.
I must have gained weight as this made me breath less and fall asleep 💤
Never thought the losing weight process from bio-chemistry perspective. Great presentation!
Just realised when I was loosing my weight , i had extremely bad breath . It was unusual as I never had bad breath ever in my life. This explains it !
Wait… this is so crazy because I was wondering the same thing. Every time I’ve lost weight, my breath always seemed weird. I know people talk about “keto breath” as well.
They couldn't have given him a bigger table? 😂
us aussies like showing off the fact we can acomplish almost anything on ya standard outdoor BBQ camping table
Didn’t know there was such a standard for tables.
Sarah Kozak.....Your comment made me laugh way too hard! 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
NO.
The table used to be bigger, but it lost weight.
Anyone else praying it all comes together in their heads at the end? 😩🙏🏻
awesome info! i have always love eating and that made me lose weight super hard, tried a lot of diets and exercises along with it, but what made it possible was agoge diet. it changed my life. its always about the right diet for u
This was a fantastic presentation! Now I'm going to watch this again!
Amazing, why am i only seeing this in 2019?
They tried to hide this from us brother, but we found it, 2019 is going to be the year we pull the cloak off the cosmos itself and stare into the heart of existence.
Because you haven’t looked. This is obvious.
Bernardino Franque exactly
I've watched qute some Ted Talks in my Young life, but this comes so late.
This may sound like a conspiracy theory...
All this 'new' information, particularly about diet and medicine, has been hushed up by the food industry (can you imagine the problems caused if the public stated demanding that HFCS and sugar be removed form the foods we eat), the pharmacological industry, and the weight loss industry for years. The drug companies have no interest in you learning how to live without their drugs. That's why we haven't seen a disease CURED in almost 50 years. There's no money in curing a disease, but plenty in 'managing' it... Why sell one pill that stops the disease, when you can sell a lifetime of pills to extend that person's life? And who funds most medical research, and medical training facilities, and offers fantastic incentives to doctors to prescribe, prescribe, prescribe?
The 'weight loss' industry is worth BILLIONS a year. A lot of that heads back to the treasury as taxes, so government has a strong incentive to 'leave sleeping dogs lie' (and paying tax)...
The food industry has lobby groups whose specific task is to ensure the government does nothing to alert people the wool being pulled over our eyes.
I am now seeing more and more videos, TED talks and promotional videos basically trying to take down all these barriers to 'truth'. A film-maker in Australia made a controversial film regarding high sugar diets. It was pointing out some really interesting information. The Australia Medical Association had the film pulled off Netflix as 'misleading and dangerous'... What they didn't say was that it was dangerous to the incomes of the drug companies who support the medical industry...
As I said, sounds like a conspiracy theory to me, but remember, a few 'conspiracy theories' have actually been proven to actually be the truth... So, 'please consider'...
**breathes aggressively**
Good one.
So does breathing make me lose weight?
@@sakanablesakanable more like losing weight makes you breathe
eat more move less keep breathing
@@sakanablesakanable Of course! A qi gong grandmaster once told me that my overweight was caused by breathing problems (sinus and lung problems).
Wow! That was mind blowing. I never understood weight loss in its purest form. Thank you!
We need teachers like Reuben. This is the best illustration of weight loss.
I have watched this ten times. I have practiced it for the last 21 days. eating one meal a day and average of walking almost 5 miles a day. I have lost 15 pounds from 260 to 245. my goal is to get to 225 as I am 6'5" and 60 years old. this is simple mathematics. I used to do the atkins diet but it gets boring. this way eating less lets me eat anything I want, but I only eat a little and I exercise a lot. pay attention to this informative information. I have recommending it to many people.

What an excellent presentation, well done and thank you for simplifying these facts on how to lose weight.
Some people eat the same amount of food and have the same level of activity, still some gain weight, some lose weight, some stay the same. There are multiple factors to make this happen, for example, gut microbiota, genetic set up, hormones, etc. The human body is fascinating.
Fascinating and sometimes unfair 😂
Having the same activity level doesn't mean using the same amount of energy. If you eat the same amount and burn the same number of calories it will be equal.
It depends what you mean by the same amount of food.
Many people confuse calorie deficit with calorie requirements. Calorie requirement is the thing that varies greatly depending on your body including size and hormones, but every person will change by a specific amount with a specific deficit
PhD biochemist here, eating less is good but you'll also feel hungry when ur stomach is empty. So I think rather than changing the volume its more effective to change the content we eat. Instead of eating high energy food like sugar, u just eat more veges that cannot be absorbed and get pooped out. Veges are also good for your bowls so double win
Yes and constantly lowering your calorie intake will cause your metabolism to slow down too so your weight loss will come to an end and leave you with a slow metabolism. You will still be overweight and will put on weight eating less than when you started
@@gordonpaulsen7359 i dont think a lower calorie intake will slow your metabolism. perhaps if u lose a lotta muscle mass then ur body's consumption of energy also goes down. so that's when muscle-training and high protein food (to increase muscle mass) will be beneficial to weight loss
@@gordonpaulsen7359 The speed of the metabolism is not directly linked to your calorie intake. It is a factor, but a VERY minor one. Something that Slimming World, Weight Watchers and these kinds of ridiculous diet programs have abused and exaggerated for their own success, and to the detriment of their customers.
Weight loss does simply not just come to an end by reducing your calories, so I'd highly (and respectfully) recommend doing some more reading on this before making statements to your friends such as this one, as they only do more harm.
@@markwillis1045 I have done research on this topic and believe my comment is correct. If you're interested, listen to Dr Jason Fung's talks on fasting vs reducing calories
You would think a PhD biochemist could spell bowels.
What a beautiful method to communicate scientific information to common audiences. Amazing teaching skills.
A fabulously witty educational experience, I am now hungry (😂) for more. Thank you very much for your educational gift.
Lol I love this whole explanation and I learned so much without even getting bored for an instant, AND understood all of it. This guy is the best.
Wow.... thank you for bringing me back my uni memories studying biochem which i thought I understand more about the chemicals reactions between C - O & H... your profound explanations where body weight loss goes to is amazing. In fact, i will apply to explain or let my clients understand how important breathing than sweating out during physical exertion such as exercising. Thank you once again.
Saw this video years ago and so glad I found it again. 🙏 Amazing research. Thank you for sharing.
Bro this is wild, love it. This would've motivated me in school if teachers taught like this.
literally the best tedx talk ever... and pretty much is the simple answer to an entire industry, i will be explaining this to anyone how asks the question, how do i loose weight. It baffles me that we can't just answer these simple questions with sience and instead just make up all this missinformation and weightless arguments, with no meaning.
Excellent presentation. I got lost in the weeds during the chemistry portion of the show, but overall I understood the very simple message which, turns out to be the same equation we've really known for years and years and years - eat less, exercise more, and breathe. Got it. Thank you!
How many people can live in a state of restriction (eat less) in a sustainable way for the rest of their lives? Not many. Then the overweight person is blamed and judged for not being able to live that way.
@@canterlevi most people can. That's why most people aren't obese.

Thanks Ted X for that great lesson, it is breathtaking.
What a great explanation that was!! Amazing!
I knew exactly what happened to it and how we got rid of it.
.... but I wouldn’t have been able to explain it in an engaging great talk and with a lovely simple explanation.
This is very interesting to me. As a side story, my family and I recently visited the Colorado Rockies (11,000+ ft.).
Now the 1st day of the trip was spent at around 6000 feet. and I was surprised that I had forgot about the lack of oxygen I might encounter at high elevations, being from Fa.
It had been 20+ years since I had been in Colorado and the one thing I forgot about was elevation and the breathing issues.
But luckily my wife had a phone call with a friend who lived in the state, and she suggested we drink a lot of water.... (H20), which provided the extra oxygen we were missing... and it worked.
No more breathing issues. Thanks and Great TED!
Wow, that could actually be a helpful tip for anyone doing something like that! I would have never thought of that.
Sorry but drinking water does NOT provide oxygen for breathing. You're unclear on the physiology. In order to make breathing easier, there are only 2 ways - more oxygen IN THE AIR, or less activity (need for oxygen). Drinking or eating food or drink that contains oxygen thinking it's going to help with high altitude breathing is woo.
@@spocksvulcanbrain Acetazolamide helps as well
If I’m not mistaken, the problem with altitude (hypoxemia) has to do with the fact that overbreathing to help make up for less oxygen at higher elevation also effects blood acid-base balance by making the blood too alkaline (low CO2). The kidneys try to compensate for this by the excretion of bicarbonate ions (a base) in the urine. The drug “Diamox” (acetazolamide), a renal carbonic anhydrase inhibitor) mimics this process, by aiding in the excretion of bicarbonate ions, thereby allowing greater hyperventilation and more oxygenation. The primary trigger for breathing (respiratory drive) is not the lack of oxygen but the abundance of carbon dioxide. Carbon dioxide in the blood stream is in equilibrium with carbonic acid. If we breathe off too much CO2, that partially extinguishes our reflex to breathe. The kidney’s effort to compensate for this to acidify our blood stream allows us to breathe more. This is why exposure to higher altitude causes a well-hydrated individual to diurese (pee more).
The water helps because of the low humidity. You're constantly losing water to the air. The last thing you want is to be dehydrated and hypoxic. Water affects the former not the latter.
So complicated yet so simple. Love it.
“To lengthen thy life, lessen thy meals.” Benjamin Franklin
Skip a few meals & snacks. Treat added sugar like alcohol (the body doesn’t need it, use it on occasion). Think when you eat...about what you’re eating. Eat well, be well.
nice upload there are many good info here wondering the same questions...
. Also today while searching the topic i learned the difference between
Physical activity and exercise
Physical activity is simply any movement that uses energy. Walking up stairs, lifting boxes, folding laundry are all movements that use energy and involve different parts of the body.
Exercise is defined as "physical activity that is structured and done at a specific intensity for a length of time." We engage in exercise for fitness and health benefits, to improve some components of our physical well-being - cardiovascular endurance, muscle strength or endurance, flexibility, body composition, etc.
The best explanation on the topic i ve ever heard , congratulations.
I've been waiting for a few minutes to stop this and go to sleep but I can't. This is one of those GREAT Ted talks
Amazing. We presented. Easy to understand.
Thank you Ruben.

"we*re in the middle of an obesity epidemic, I don't need to tell you about it."
*burn.*
People enjoy eating. It's a fact of life.
ep·i·dem·ic
a widespread occurrence of an infectious disease in a community at a particular time.
So...we should stay in our homes, so we dont catch it? Exaggeration is a disease, by your usage.
@@longdong982 so obesity is a widespread lifestyle disease and prone to infect others, or an epidemic as you yourself defined. One can catch it through neglect and some thought patterns (memes) can be used to spread it. Thus, it isn't that crazy to quarantine yourself from other people (both in real life and in virtual life) or things that will make you more likely to become obese. CZcams search "This videa will make you angry" which explains this better than I can.

We just got told
One of the best Ted Talks ever because it was so practical
This was so throughly educating and enjoyable. You definitely break it down into simple terms and make it very easy to understand. I enjoy chemistry and have a good background on it but learned a few things today. Thank you! I did watch a video a few months ago (I don’t recall from where, but they explained where our weight loss actually went. But it was nothing compared to this! This was so educational! And fun.
I knew it all along. Anxiety burns calories.
It does if your anxiety leads to reduced appetite ;)
If that was the case I’d be skin n bone 🦴
IF ONLY! I’d weight 85lbs if this were true.
@@staceytroffer8287 same...wish You all the best and no more stress in life💝
am in lockdown for 2 months in Malaysia n worries are burning my fats because of overthinking and I can see it in the mirror. Just want to go back to my country
"you eat sunlight"- LOVE IT!!!
It's odd that he said that after making the point so strongly that we don't actually turn our weight into energy, well then we don't turn energy (sunlight) into our body weight either.
@@bxdanny Yeah that was one of the dumbest things he said. The living things on the planet gain low(er) entropy energy from the sun, and emit high entropy energy (heat), so it's basically about maintaining a 'workable' level of entropy with the help of the sun.
@@bxdanny he didn't mean it like that though. He said that just to be cute. Techincally we are eating sunlight somewhat kinda since it is what plants use to bind stuff with.
The energy we consume through our food is in the molecules, but not in the mass of the atoms therein, but between the lines: It is the indeed the energy that keeps these atoms tied together and gets liberated and exchanged when atoms swap places during the chemical processes of digestion and metabolism. Matter is but the (necessary and handy) packaging for energy, so in that sense it is absolutely correct to say that the energy in our food is equivalent to sunlight.
He meant that we are fuelled by sunlight, and the molecules and atoms are merely carriers of this energy.
A TedTalk that changed my entire perspective, beneficially!
Very talented to put science in a simple language , Amaaazing 🥰 Thank You 👌👌
the 16% lost as water is mostly exhaled as water vapour, that's how cellular respiration works
No that's not solely respiration that's to do with diffusion / osmosis to a cellular membrane AK the lung air interface. It's got nothing to do with the respiration part. Respiration part produces the water. The vapour part happens in lung due to things to do with relative humidity and temperature differentials but I won't bore you with that
Brilliant man. I have ALWAYS wanted to know this. I could never find the answer until now! THANK YOU!!!
Absolutely brlliant. I loved it.
As others said - IF ONLY we've had teachers like him in our primary! :D
Great information. Watched it a while ago and came back for a refresher.
I need to put that on my wall in big letters - "EAT LESS-MOVE MORE-KEEP BREATHING". Wow-what a concept! That should be a required poster at every buffet.
That’s a horrible idea
Wow! Loved this talk. One of my favorites.
Eat less, move more is truly the key to losing weight. That’s been my go to phrase for years. When people try to over complicate, run! Great talk!
literally run, hahaha
@@vishalreturnsgmail Right! lol 🏃♂️
I honestly enjoyed listening to him!
I wish you were one of my teacher before!
