Human bodies aren’t built for extreme aging: our capacity is set at about 90 years. But what does aging really mean, and how does it counteract the body’s efforts to stay alive? Monica Menesini details the nine physiological traits that play a central role in aging.
Lesson by Monica Menesini, animation by Cinematic.
I swear to god, there's a TED-Ed video for every single question that I've ever had.
Except for the question "If I order all possible questions in alphabetical order, what would be the answer to the first question not answered by a Ted-Ed video?"
Q. What's the meaning of life?

Human curiosity is everywhere if it is not suppressed by irrationality
zonkeymaker i see what you did there ( ͡° ͜ʖ ͡°)
You need to think more, no offense.
Watching this video made me sad. It reminds me of my mom when I was young she used to be in charge, she was your everyday strict asian mom, she taught me discipline, she was in control. Now I look at her and she turned into a jolly old woman and recently started forgetting things. It pains me to see someone who was a powerhouse loose her skills as years go by. She still has her wisdom but I'm scared of seeing her turn into a helpless old woman. Its like watching her slowly die before my eyes and I can't do anything about it.
I feel you 😔
If she's not sad, you shouldn't be either. :) Celebrate her as who she is now! Don't bury her in your head just yet. She has so much love to give. 🌸
You don’t have a different fate
I cried as i 'm reading your comment
This is my grandma.
I wish my parents to live a very long life
Mine too
thats good stuff good to see
We all do
Seems you have a good parent
I dont want it
I wish so too
I remember my biology teacher in HS saying aging is kind of like you having a VHS and making a copy of it, then making another VHS copy off the first copied VHS, then making yet another copy off the second copied VHS, etc.
The quality will get shittier shittier and that's kind of what your cells do as the regeneration process gets poorer and poorer. I think that's what they're talking about at 3:50.
❤
What a great perspective of ageing
GenZ will not get this explanation haha
@@cassiosiquara To give a more Gen Z example, you also get that effect with screenshots I believe. A screenshot of a screenshot of a screenshot etc. decreases quality over time. But to be fair the last time i tried that was years ago, idk if software has changed since then lol
@@thedarkone7887 Screenshot doesn't decrease quality, you may experienced that because of image compression of your OS / software. We also may get that effect with pictures of pictures, but is not neat as the VHS explanation.
Aging and dying sucks.
yep
but do they swallow?
How do you know that it sucks if you've never tried it? :D
you wouldnt be here comenting if organisms didnt die.
There would be only a lot of simple unicellular organisms that would never evolve
Nah death is a man's final reward.
Mitochondria is the Powerhouse of the Cell.
You sir deserve a cookie :)
+Lejinad69 Madame and thanks. :)
Don't stay in school
Omg my teacher says the EXACT same thing!!!
_Mitochondria_ is plural. Singular is _mitochondrium_.
Getting old is probably the most cruel thing to ever happen to you. It’s worse than losing your love, family member are going broke.
I agree. Aches and pains, health problems, and not having all the huge abundance of energy and strength you had when you were younger. Not to mention the burn out they may suffer from all those years of work and labor.
Taking care of yourself and exercising on a regular basis is the most important thing for your well-being.
I take care of myself for myself and so my family doesn’t have to worry about me in the future.
A little off topic but I love the style of whoever did the art! It's really cute. ^^
Same here!
yay! I'm not the only one who thought so!
same
+Dark W Yeah, his progressive house music is pretty good, I'll give you that.
+Dark W How the hell does liking art make people weebs? This has nothing to do with that.
OK, I'm kinda sad after this video.
I wouldn't be. There is a very real chance that we will have taken care of most age related degeneration within the next 10-15 years
I wouldn't be surprised if the are many people today that will live to become 150+
And under that time the science of all this will have evolved more. Maybe enough to postpone aging indefinitely.
This reminds me of what Adam Savage once said, something about our brains not having enough capacity to store all the memories of our indefinite lifespan
Paul Wong
Guess we will see with time. But it dont think we know enough yet to say that
I hate it that many people fail to realize that. I mean, I'm really optimistic about this and I really think I'll live to see the next century at least
+Paul Wong We could just augment our capacity, like an upgrade for storage on a computer. Eventually, of course...
I'm really afraid of getting older, which means I have to leave my parents and face more and more terrible situations

Well you better get some help cause it’s gonna happen

It is something we all have to do, it is not all bad.
When you are 123 years old, 1 million will do nothing for u
that's right
No unless you already are rich which is likely
1 million will definietly not benifit you, but surley can benifit your kids..🥵
By the time i turn 123 there mostly likely will be more advanced technology that would help me enjoy that 1 mil

Nah
Did anyone else get atleast little sad about this video?
Nope, you are the only one with feelings on the Internet
Nope, only thing i had was hope, and i lost it after watching Infinite Warfares trailer.
ya
yes
I'm 22 and now I feel like I've wasted so much of my life fuck sakes xD
This tells HOW we age. Not why. I thought this video was going to talk about the reasons why nature ages and why some things don't "like the immortal jellyfish, some bacteria, and plants which can die and revive themselves." Why do humans simply die, when other organism live centuries, nay, forever, unless killed by an outside source. Still a good vid though, but I'd change the title.
Thats exactly what im lookin for lol Why,, NOT How
True. I still don't understand why those things mentioned in the video happen. Like, why can the body not fight off all the deterioration? Why, when it is getting all the food (nutrients), can it not replenish the same way?
@@purplespark8 your cell stops repeating itself
Uh, isn't the immortal jellyfish also die? Like they aren't able to avoid death. Sure they'll revive, but in order to do so they need to die first and than regrow from themself afterward.
Idk, that's just my thoughts
If I could live to 120 and my body stopped aging at 23 I would be so happy. I miss my young body 😭😭😭
Why do the prophets peace be upon them pray to God Almighty just like Muslims?! 😳
Abraham peace be upon him
Abram fell face down and God said to him: for my part, here is my covenant with you you are to become the father of a multitude of nations
genesis 17:3
Moses and Aaron peace be upon them
But Moses and Aaron fell facedown and cried out, “O God, the God who gives breath to all living things, will you be angry with the entire assembly when only one man sins
joshua peace be upon him
And Joshua fell on his face to the earth and worshiped
Joshua 5:14
Jesus peace be upon him
After walking a little farther away from them, Jesus fell to the ground and prayed, “My Father, if it is possible, do not give me this cup of suffering. But do what you want, not what I want.
matthew 26:39
Even the angels, peace be upon them, in heaven worship God Almighty in this way!
And all the angels were standing around the throne and around the elders and the four living creatures, and they fell on their faces before the throne and worshiped God

Yeh dear
Imagine everlasting youth ... Imagine if we had limitless time ! : )
I wish we can stay forever young 👍🏻👍🏻
Same here
Same I'm 20 and I don't want to get older its hard to accept the truth
You’re young theaux not forever :(
That would be so boring 😁
Actually I don’t agree, because what are we getting is so enough for us, think about it like some people live a happy life so they don’t want to die and others live sad lives because of the difficulties of life or because they were born in a poor country so they want to die. Actually some people have already suicided because of their bad lives but the death makes all humans equal and it’s the only thing that all humans are equal with it, and we don’t know what is waiting us after this life, maybe another life or heaven or something more interesting 🙂.
Since I was born, my ultimate desire has been immortality.
honestly same
that and burn down the national bank
@@superbuuinyourrecommended xDDD
You have no idea. I'd rather die than see my children die. I'd rather die than see so many friends die and never go with them. Immortality is for people who are scared of death, people who don't understand life. People who have no faith in God. Your body is NOT immortal but your SOUL IS. You already are immortal in the best way possible.
If you achieved immortality, then 100, 200, 1000, 5000 year will pass or however many ions and ions after that at one point your only desire would be death.
Same I fear death to much and it would just be cool to be young and never dying
I love the art style of this video! Would love to see more of it in future videos.
Without that little voice in your head, you wouldn't be able to read this.
u just read my mind @@
mind blown
holy shit............my mind just exploded.
True
ikr
people don't want to live longer, they want to live YOUNG longer... jeanne calmant last 20 years wasn't a blessing.
stem cell is the solution of everything...EVERYTHING !
Stem cells are a big part of the picture yes as are telomeres/telomerase. These three approaches might be made to work as a combination to reverse much of the dysfunction aging causes.
Why aren't we funding this?
Karl hanes lol u think the ppl in command want the whole world to be able to have theyre hands on this , no , let the mass die out, n omly the rich n with power will be able to afford these types of benifits
@@karlhans6678 we are actually funding this. There are many groups of scientists working on aging.

Once I was studying the brain processes and my professor was talking about Alzheimer's disease and explaining why it's more likely to happen when we age and at the end of the explanation he said, with a kind of weird, gray and at the same time lovely glance at the board (he loved teaching): "it is like if our bodies were programmed to die...". I twas like if he was just thinking out lout. One day I'll probably forget the lecture but I don't think I'll never forget that moment
Thank you for making me worry about my age although I am only 24
Now you're 27
I'm 15 and this already gave me anxiety...
Aren't you 27 years old?
I’m 18 and I’m worried too haha 😢
I'm 19... Soon to be 20....
There are some really fascinating case studies about communities in Okinawa, Japan and Sardinia, Italy (the two world communities with the oldest average ages) regarding diet, lifestyle etc. for those interested in potential contributors to longevity...

Great info as always, but loving these animations lately!
Now I'm nearly seventy - I live every day as if it were a precious gift. I'm not concerned about living longer; I want to live well.
How can it be a gift. It is a curse. I wasnt asked to be here and now i have to deal with it. Loneliness, getting old, etc...

Wow, this video is really packed with a lot of useful information, thanks to TED-Ed video I know a little bit more about why our bodies age, an also help me to appreciate life more an all that it has to offer.
Monica Menesini's exploration into the science behind aging is both enlightening and thought-provoking. Her ability to break down complex biological processes into understandable concepts makes this video not only informative but also accessible to a wide audience. Understanding the mechanisms behind aging is key to unlocking potential solutions for a healthier and longer life.
How could TED-Ed read the Questions in my mind. Bundle of thanks for answering to all those questions.
Wow, it's awesome lesson, thank you for sharing 😊
It is because we know we are going to die that we try to find purpose in living and living life to its fullest potential. So don't be bummed out about aging because it serves as a reminder of our limited time alive.
Also, as we get older, you can say that you replace your physicality with wisdom. It's like an exchange; your body for your mind(except in mental diseases that come with age). As we live and get older, we will learn and experience many things that will eventually add up to our wisdom, which we try to pass on to the next generations. I personally believe that although undesirable, aging is very vital to the human experience.
well couldn’t you have more meaning if you lived for longer? if you were immortal you could find infinite meaning because there would always be something to do
@@wren_. why not sleep for 2000 years if you live forever?
@@LeftCaptain well said
@@wren_.no because eventually you’d run out of things to do… what else can you do on this small blue planet except work and travel?…
@@LilXancheX People find ways. This could be one of those times where your creativity shines. Boredom is often the best motivator. It could be used as an opportunity to build new habits, try new things, form new relationships etc. Imagine if Walt Disney was able to live forever. Think of all the things he did with the years he lived. Now think of the things he probably could be doing right now, hypothetically. Theres always something knew coming. A new movie, knew book, knew celeb, knew resorts, knew scientific discoveries or breakthroughs, etc. There is ALWAYS something to be made with the time your given, even in times of sadness or boredom. You just gotta apply yourself. Nobody can do everything you know. Its impossible. Theres always many many many many things to do in "this blue planet".
Thank you for your video. Both content and images are very interesting for me.
I was genetically programmed to die. Wow, thanks life.
Science is so complicated yet insanely intriguing
Thanks for counting the days! Some days feel long and definitely count and should be counted when giving age! Some minutes and even seconds count!
I go through the same thing when I’m either sleeping, resting, or sometimes even walking!!
I like to think about it as the law of our universe tending towards entropy. The combination of our atoms forming together itself is overwhelmingly remarkable. Then, the dissolution of structure as time moves forward is just the natural flow of the universe.
i looooove how you represented a scientist as a woman of color! thank you!
Racist
Racist af
Andrew Walsh why is what i said racist? I am honest and not sarcastic at all. I think that women especially women of color are not represented enough in the media. I am a feminist and i definetely did not want to sound racist at all. Im sorry
Nightcore Lab why is what i said racist? I am honest and not sarcastic at all. I think that women especially women of color are not represented enough in the media. I am a feminist and i definetely did not want to sound racist at all. Im sorry
Her statement was not racist guys. She was just pointing out how TED ED represented women of color in a positive way.
i love the artstyle!
Love your vids I get to learn and show off my classmates
Amazing lesson.
I got sad. But then, this video kinda make you want to go out there and experience life while we still can.
When asked about her recipe for longevity, she attributed it to olive oil, a glass of porto and chocolate. Nevertheless I am certain that all causes enumerated in the video will be "cured" by science and technology. It's only a matter of time.

Great, now if only you could say that and prove it instead of nerdgasming at this because it fits into a science-fiction story trope.

Thanks to the internet, researching medical and health resources has allowed us to live a longevity healthy lifestyle. I see seniors today that do not even look their current age. Couple weeks ago I read an article titled: "Aging in Hollywood." What caught my attention is how actresses mentioned when they hit a certain age; and their looks begin to fade, Hollywood pushes them aside for a fresh-looking younger face.
Yeah because they're career is mostly based on looks. If your looks get bad and you are in an industry where mostly looks are required then you are not going to be enumerated in their movies.
@@Dark-NETwcry A veracious comment.
This question never gets old.
When ever I look back the old photos when I was young I cried cause I wish I could travel back and I don’t want to get old
122 years? Pfft! I plan on living for ever!!! So far so good :)
not for long :")
I know this is a joke, but:
Your "plan" will never come into fruition.
Before we work on how we could get older than 90 years, we have to work on not destroying ourselves within the next 40 years.
the last line was so beautiful
As a slavery of depression and anxiety this would be nice to know that all things come to an end.
Does anyone else fear death or wonders what happens after, or is that just me? 🙁
Same here
Believe in Islam and the Qur'an. May Allah guide you.

Same :(
You become sustenance for other organisms. So therefore, you continue to exist in some form or another.
Do you remember what it was like before you were born? Before the cells that make up you even existed? Nothing right? That's how it'll be after you die too-- unless you want to believe in spirits and stuff. You didn't have a consciousness then and you won't have one after you die, so make the most of your small life while you can!
Thank you so much!
Informative video explaining this important topic.
My grandfather is 91 years old. He has very few wrinkles on his face and his beard is not completely white. He is still sharp minded. He is still alive and living with us. He is much healthier than the other old men۔...... And my grandmother is also alive she is 80yrs,she is more active and helthier than my grandfather but she have more wrinkles than him, she react like girls😂, she still has a sharp mind.
Ok, it’s 12 AM, I need to go to bed now.
“Why do we age?”
Yep I need to watch this
As i watch ted ed vids, my vocabulary improves
Life is beautiful, it is fleeting so transient...
there's no escape from death
Going through the comments section was a great way to start my morning!
I saw you before. Its interesting
There are 3 things that we can't avoid:
1. Death
2. Get old
3. Tax
getting old and death is basically the same thing, and tax can be avoided if you live without money. some people did that, they grow foods and exchange some for clothes.
and also, we technically avoid death in our every living day lol
you don't avoid death every living day but you get closer to it
Question! Since exercising basically promotes muscle repair and cell growth, does that mean our body gotta spend energy and work more to achieve this and hence shorten our life span? (Similar to a machine being used more and so break quicker)
The cell aging would probably not outweigh the benefits of exercise
Shoutout to everyone who is educating themselves
That animation was adorable.
This is video is amazing , it encouraged me to stop chocolates and toxic food , really convincing 👏🏿 😍
122 years..? I don't want to live that longer. I just want my life to be ending happily.
Best to listen to ted ed when sleeping
Loved it 😍
hello maam.. your video is really nice and the information is very suitable.. i was having aging signs and that too at a very early age.. then i tried using planet ayurveda anti aging products they really made a difference and they also guided me proper diet and lifestyle..
Freakin' Telomeres, if we could solve that problem we could solve everything else about aging, the rest of it is potentially treatable. The Telomere problem is like a hard coded limit we must overcome if we want to modify our lifespans beyond a certain point.
if the telomeres are too long, your cells become like cancer cells
if the telomeres are too long, your cells become like cancer cells which are immortal
Our cells can already regenerate part our "lost" telomerases. Stam cells, reproductive cells and cancer cells have the ability to regenerate the telomerases to the orginal full length. But the idea to know that our evolution made the choice not to have the ability to regenerate and thus stop aging. So it is also good to think if it is indeed good to stop aging of we could.
YiGzit
Telomere degeneration has been a non-issue for most of our evolutionary history because human lifespans rarely reached the point that it was relevant.
Evolution didn't "choose" to place a hard limit on our lifespans, if someone were born with a life extending mutation that would allow that person to help rear more successive generations of offspring which would likely be an evolutionary advantage, assuming they retained their health as well.
Even past the point of reproductive viability, the elders of a family often play an auxiliary role in supporting family, providing means that they otherwise wouldn't have.
That is true, remember there are partail and fully immortal organism out there.
Thank you
I swear to god Ted Ed answers all the questions I've never had!
I love the animation style, especially the diverse characters 💗
To live longer, don't hate, be positive, watch what you eat, stop drinking and smoking, avoid coffee, get enough sleep, reduce friends, learn to be alone, do things that makes u happy and smile more, drink gallon per day of clear water. Exercise lift weights and do cardio
Earning decent money and not worrying about bills is a MASSIVE entity. Money doesn't solve problems but my god does it make life so much easier.
I love the art
M’y mom is 63 years old hamdollah and she looks like in her fourties recently she did a operation on her knees and recovered very quickly in contrast to me even a small injures could take time to recover i and even I have some freckles under my eyes And iam only 25 years old .my immunity system is not powerful .now I understand that we should take care of our health in order to remain youthful thank u these questions were creating a debate inside my head
they didn't mention that calment (the woman who lived to be 122) was a chain smoker. i find that ironic
is she tho
Was she*
Isn't that is drawn on 0:08?
She is smoking!
She wasnt a chain smoker she only smoked 2 a day buddy
when your your so old you see the turn of two centuries
I saw the turn of a millennium :-*
I saw the turd of a millennium
no not at all 2 days old babies could have seen the turn of a millennium
I was made before Egypt.
I was born in 1999 so I'd increase that to 2
Finally, I found!!
Plz make a video on why do we die?
In most cases people used to think of the things that did not happen or are stuck into the memories that had happened. Either in past or in present which is impermanent. Realizing the constant may help us to not age. Constant is Present. Present never dies. Only the past die and the future will die. Realizing NOW may solve the problem of not aging.
Age has always come down to genetics! If mom or dad lived into their 90s you may too. Just like cancer. My parents both smoked they never got cancer. Heart disease and emphysema yes. But never cancer.
TED-ED thanks for the diversity in this video!!!!! Plz keep on doing it and you will improve the circumstances of eguality
I love you TED ED
I swear when I watch one episode I don't stop
The circle of life is beautiful 🙌🏻🙌🏻🙌🏻🙌🏻
Omg I just thought about this question😶 what a coincidence😀
It's what you put in your body young will and dose affect you in the long run being mostly deprived of basic things and place in areas that are clean you can achieve better things
Excellent.
The most difficult thing I have encountered growing old is having to see your good friends die,but it sure beats the alternative.
so sad
Taking college bio makes this sort of a review, very interesting stuff
Great video!
thank you very much ted ed... but i have a question... basing it to our teachers that nerve cell dont replicate that why as we grow older we tend to lose a part of our memory... but looking at just 3 second of the video you shown us that nerve cell replicate... kindly please explain it for me please... thank you😀😀😀
