Why do our bodies age? - Monica Menesini 

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?"

You don’t have a different fate

I cried as i 'm reading your comment

This is my grandma.

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

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.

You sir deserve a cookie :)

Don't stay in school

Omg my teacher says the EXACT same thing!!!

_Mitochondria_ is plural. Singular is _mitochondrium_.

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.

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.

isn't dying young worse than getting old?

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...

Same here!

yay! I'm not the only one who thought so!

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

@@shawneamarrow4082 😂😂😂

It is something we all have to do, it is not all bad.

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

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 🙂.

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.

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.

Nice

Now you're 27

I'm 15 and this already gave me anxiety...

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".

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.

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!

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.

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...

The cell aging would probably not outweigh the benefits of exercise

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

not for long :")

Late answer: shoes are much easier and cheaper in maintenance than dogs. They tend to be quite quiet and slow, but that's OK for elderly people. An agile dog is usually too much for them. A cat or something smaller may fit better, but still cause physical work.

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.
