  • why cant we see the top of the monkey's head? using animals in researches should be banned. they dont need any of these stuff. we should use humans.

  • It's actually research for people with disabilities.

  • more like the monkey uses his arm to control robotic arm.....

  • DURR IT'S ABUSE CAUSE THE MONKEY NEVER ASKED FOR BIG ASS RIPPED ROBOT ARMS HURR

    inb4 he never asked for this

    but seriously, why couldn't they've taken me instead dat looks cool as hell ;_______;

  • @LidlFisken

    Lol I wouldn't mind being kidnapped to here and be forced to feed myself yummy with an awesome robotic arm

  • how is this abuse?

    monkey is enjoying its food!

  • Now that's a badass meal... I mean, look at the monkey's face!

  • Guys lets make a fuckin robot arm

    -ok

    Dude lets make a monkey controll it!

    -so he can eat marshmellows?

    Yes

    -nobel prize

  • 脳がむき出し?グロいから隠すってのもわからんじゃないが…それ­にしても凄いっていうか、ちょっと怖い

  • すげええええwwwww

  • That monkey gonna get fat D:

  • arm! moooove fasteeer! me is hungryyy!

  • Cybernetic Monkey eats 40 pounds of Bananas

    Film @11

  • @schicksta1 You are right about slaughterhouses and not only.

  • There's a cable running into their brains, where a small chip is capturing the information needed to control the arm.

    It's not wireless, it's not painless and the chip will only last for a few months.

    Clearly, this isn't as painless as some ignorant douchebags commenting on this video seems to claim.

    Wouldn't go so far to call it inhumane, as the other camp likes to do, but clearly this teaches us that most people are stupid as fuck.

  • @Munkatten <----case in point

    

  • @Munkatten

    Don't call people stupid when you're saying things like a chip is "capturing" information. You obviously know nothing about this, electronics, robotics or control technology. If the monkey was in any sort of pain it would'nt be happily sitting there eating. To be perfectly honest, even if a monkey is being hurt, I care much more about the extremely sophisticated robotic arm being developed as a result of it.

  • @MarshFacev2

    Capture: to gain possession of.

    It's actually correct to say that the chip is capturing information. When you're talking about sophisticated electronics, metaphors and abstractions are a necessary evil, for someone pretending to know, you come off as extraordinarily ignorant.

    Then you assume that I'm arguing against the use of live monkeys to test new technology, which I'm not, especially not in this case where it seems both extremely feasible, and extremely useful.

  • @Munkatten and how would you know this? you show me some solid proof than ill be like 'aight respect' but you dont have any!

  • They are just a bit below our level of intellect, and yet they can use our technology.

  • why do humans hate anything to do with nature

  • monkey UUSE the FOORCE!

  • 5 people think this is animal cruelty!

    lol i mean comeon the monkeys gettin fed like a king and is using a ballin ass pimped out robotic arm to boot!

  • @AiBhai[ let's confine your dumb ass to a seat and strap you in. and put a microchip plant in your dipshit brain so we can control your movements. You will live your life in a cage, no fresh air, no exercise or sunshine or contact with another person ever again.you will shit and eat in the same place day after day..then they will chop your head off when they are done with you so they can study your dipshit brain..but hey- you WILL BE GETTING FED LIKE A KING! fucking moron

  • @shantiz123 aight punk

    first of all, theres no chip IN his brain.

    second of all(and this ones really obvious{dumbshit}), the monkey is not having its movements controlled /duhhh/ the entire point of this video is to show that the monkey is controlling the robotic arm while still retaining full control of its body.

    third of all, when they do testing such as this, the animals get plenty of sunshine, exercise, and contact with others they also dont chop off their heads. you are clearly very stupid

  • @AiBhai have you ever even walked into a lab? i am part of an animal welfare coalition and clearly you are ignorant..Please inform yourself. the animal is a complete hostage and the neurology of these monkeys will be studied-that means killing them and examining the brain..it is so evil these labs are subterranean-(um that means no sunshine if you don't know) & they are kept in tiny stainless steel cages.you are a dipshit-this is about "behavioral control through manipulating neurofunction"

  • Hahahaha the moneys like "Fuck yes!"

  • I am a HUGE animal rights activist, along with many other things humans do...

    HOWEVER.....I do believe the human comes before the animal in the case of amputees.

    After all, soldiers who serve to protect everything everyone lives for deserve to live a better life than monkeys.

  • When a monkey can start communicating its subjective desires for self preservation, I may just shed a tear for this little #u@$er. And in regards to kiddish10's statement on what could be more cruel than this..? Well, hmm, maybe Mao, Stalin, and Hitler and their totalitarian monster of government they made. Normally, I'd insert a statement about a hippy d-bag living in a drug induced fantasy world; but, its that very fantasy world that led me to have interest in prosthetic technologies.

  • Just remind one of good old philanthropist Pavlov. And what is good for monkeys can't be bad for humans ey? Get your brain chip today and you can have intercourse and watch t-levi-sion the same time. Wow!

  • this is bullshit. this poor animal has the right to live like other animals. this motherfucking scientist should not enslave him and should let him go free! this is pure cruelty.

  • @kiddish10 dude, its a fucking monkey

  • @sialuab i know man, but still... it doesn't seem right to abuse a monkey that way. what if you were born a monkey. then i would of course say.. oh yeah man! its a motherfucking monkey! and you lose your fucking arm in the process. cruelty does not fly! animals feel pain just like we do, and the monkey is struggling with a motherfucking robot arm to eat food! what else could be gross than this?

  • @kiddish10 its for a good cause and if i were born a monkey i wouldn't mind having a robot arm instead of not having an arm at all.

  • @sialuab yea watever man. they should start substituting monkey with a man. and thats where the game begins. then i'll surely appreciate this technology, u no... like create a real world terminator. it'll be fun haha.

  • @kiddish10 they did and are doing that already!

  • @kiddish10 There are rules, specifically rules regarding pain, with respect to medical animal testing. It's important to have animal models for technology like this to make sure it's effective and safe for humans. It seems cruel, but you'd probably feel differently if you had Parkinson's, Huntington's or some other degenerative neurological disease.

  • @ericrosoff thanks for clarifying.

  • Comment removed

  • this is the way of the future

  • look at his right arm, it's like a mirror of what he is doing with the robotic hand. Strange adaptation, weird video to watch

  • I wonder how the sensors are attached to its head.

  • sick !

  • @ProgectWander, what an absolute moronic remark, the monkeys are the trail, eventually humans will try using the same shit, for amputees or paras or quads, and the other 52 of you that gave his remarke a thumbs up, your a bunch of dumbasses too.........

  • @katosteen I'm pretty sure he was joking.

  • I know god gave us power amongst all animals but I don't think surgically inserting a fucking cable into a monkeys head was part of his idea...

  • @shadow55981 OK so usign science to help lives is wrong but believing in an invisible entity as a deity that watches you all the time like a perverted monkey is ok?

  • I gotta say they did a pretty good job in hiding the monkeys brain. I'm not curious I guess the poor monkey is fine..... Why the fuck did they hide it? Fuck u fuck u fuck fuck Disney disown did skid did diod sips diode

  • I wonder if that monkey can spank itself?

  • cmon i want to see the wires coming out of its head

  • @roofy2k Me too. You can probably see all it's brain wrinkles.

  • @Tholc501, and @AntiNWOMusic,

    I am only 14 so i can't say this for fact, but i would guess they used some sort of device on a headband or hat type thing, like new video games that HUMANS use, which are controlled directly by brainwaves. Look it up if you want.

  • I dissagree with the the monkey being strapped up in some lab but shit, it was worth it.

  • Fascinating amount of control there. Interesting to see that the monkey doesn't -quite- seem to see this arm as an extension of itself, eating of it as it might out of a handler's hand. Or it could be its somewhat uncomfortable predicament. But the fact that it -works- is a great sign of things to come. Look forward to human testing.

  • Hahaha this is so awesome

  • @SupportTheDinos and @MrArtiny:

    Why don't you look into animal slaughterhouses for animal abuse, not places where they are doing research that will benefit amputees.

    And the monkey isn't even suffering they didnt hurt it in any way they just placed things on his head without any incisions

    no animal abuse at all

  • @schicksta1

    I can't see the monkey's head it seems to have been obfuscated by the metal machinery deliberately. I'll take your word for it though, but If its so harmless, maybe you should volunteer to replace it, you seem kind of keen and at least you have the choice.

  • @schicksta1 I'm sure it's not suffering, however it does look like a brain interface was implanted. Check out the vid at about 00:45, and you'll see the wiring on the side of Mr. Bobo's noggin.

    Abuse? No. Research and development, and quite fascinating as well.

  • @schicksta1 um. they didnt just place it on his head. thats drilled into his brain.

  • @schicksta1

    "they just placed things on his head without any incisions"

    not true.

    I guess you didn't watch the original documentary on 60 Minutes. They actually cut the top of that monkey's head off and implanted sensors directly into his brain.

  • @schicksta1 And yea dickshit that just magically happened they didnt kill many others making this possible, right?

  • @schicksta1

    but those marshmellow, there a choaking hazzard you know

  • @schicksta1

    "And the monkey isn't even suffering they didnt hurt it in any way they just placed things on his head without any incisions"

    In it's head, with cables penetrating it's skull. What you said is pure bullshit.

  • @schicksta1 not to be insulting in any way but i think i read somewhere that they implanted a chip in the monkeys brain, not just a cap. but ur right to say that this technology could solve huge problems

  • @schicksta1 actually they did make incisions. they put two brain implants into his head. do ur research

  • Actually there was some surgery involved. The experiment was first conducted in a human, who had an electrode inserted into his brain, into the region of motor cortex controlling the hand/wrist. He was later able to control a cursor on a computer screen "with his mind". They did further testing in the monkey after the success with the human experiment, to see if it could be used to control a robot arm. Clearly it can be. SCIENCE IS COOL.

  • I hate when this damn ppl experiment with animals!!! why they dont experiment with their ass!!!!!!!!

  • @arelistoughlove ...well if they did that and something failed, killing them, then there would be no on to perform the tests and we would lose many valuable minds and lose the possibility of this becoming a reality in the future...duh...

  • It's University of Pittsburgh, NOT Pittsburgh University!!! Yayy that's m school, my awesome school, my awesome research school ^_^ This stuff is pretty cool

  • 50 or 100 yrs from now , human will have cybor arms and legs etc ,etc.. for amputee or handicapped pll.. knowledge is power.

  • They are not ashamed of them selves for this, you have to understand that most of these experiments have been done on humans. Check Unit 731 on youtube. Data was later traded between Japan and U.S.

  • flag it for animal abuse

  • @MrArtiny Idiot. Lives are saved by doing this. Besides, the monkey is living on easy street. Food every day, no predators etc..

  • @MrArtiny

    How about we flag you for being a derp? The monkey is fine. In fact I bet he lives a better life than most youtubers. Not only does that monkey helping with new technology that could aid amputees and people born with birth defects, but he also gets to eat while playing with robotic arms. That's one seriously cool monkey.

  • This is so just inhumane and just GAWD DAYUM so sad!! i just want to cry.. this is so sad :(

  • @SupportTheDinos ...seriously?...HOW IS THIS INHUMANE??!!...you are an idiot for thinking this. 1: its just a monkey. 2: its not in pain, all they did was put it in a box and made it so it could not use its arm. The most amount of discomfort seems to be that he gets pissed that he cant use his arm, then realizes that he has another arm to use. 3: this technology will help better the lives. HUMAN LIVES i might add, of so many people. Id say a monkey or two is worth that.

    Dont be such a baby...

  • @MaxxPowerFTW I say fuck the amputees I would've previously felt sorry for them but any amputee that benefits from this gets no sympathy from me

  • @AaronCrossNZ So you dont want people to benefit from things when animals are used as test subjects?

    Have you ever had ANY sort of medication? If so, you are being quite hypocritical.

  • Yeah its so inhuman that this monkey has to suffer through chowing down on bananas so that people/soldiers can get replacement limbs that they can control with their minds. Fuck you PETA

  • no matter what all you animal rights people say, this is legal and you cant to jack about it :D

  • @giantblue you HORRIBLE jackass

  • lol

  • Science!

  • @mololol Science again, I said science again.

  • Sick and wrong

  • @AaronCrossNZ dont be such a fucking baby...

  • please people, realize that by stringing up dogs, they figured out some important concepts about anatomy and so forth, furthermore if you're baww'ing at the poor monkey just realize chimps eat monkeys, and every living organism eats another one, or competes for the same resources as another one (sieges in medieval times are for starving out the citizens often)

    so stop bawwing at 2-3 monkeys

    notice the real arms grabbing for the food too, I wonder if training could make that stop

  • I published this video on the Dutch website WELSTIJL (11 may) Kind regards Sem Mallée

  • notice how they block the view of the monkey's head, It is cuz they drill holes in his brain and put electrodes in...very sad when i found out how scientists really do this...then they usually kill the monkeys afterward...

  • @wingedsoul Hahahahahahahaha

  • I'm a bastard I dont care for animal rights and shit, but i gotta say that flatwire on the back of its head looks kinda cruel, especially cuz they're trying to block it from sight.

  • @elkikex

    Doesn't seem to bother it, it's turn it's head around and doesn't seem to mind as long as it gets food.

    Only if people had such good neurosurgeons...

  • I can't believe this video is two years old. How the hell could I have missed that?! Thank you xkcd for bringing this to my attention!

  • i know aputees often have phantom troubles, pains/itches on the limb they no longer have so they cant stratch it or mend it. i wonder it having a robotic arm would help such things, they could scratch the arm and the action may help the brain or they could develop sensors for the arm, that might also help with not accidentally knocking into stuff with them

    anyone know about this stuff?

  • @KottonmouthSoldiers Look up the term 'haptics'. They are working on incorporating sensors into prosthetics so you can 'feel' things too.

  • @alk3v that is awesome!, thanks.

  • Today, a monkey uses a robotic arm to feed itself. Tomorrow, I'm fighting spider-man with four telescopic arms coming out of my back!

  • that is is fucking incredible

  • this is animal abuse. you must not open the head for connecting the brain. frauenhofer institute deploy a cap witch you must just put on your head

  • @petevandebeat. You know what's animal abuse? Watching humans suffer all kinds of maladies when something can be done about it. Can you blame scientists and policy makers for choosing the welfare of humans over monkeys? This is a legitimate science with tangible benefits. The scientists aren't doing anything to hurt this monkey. They're studying it in a controlled environment.

  • You obviously havent seen footage of head injury "research" at the hands of vivisectors, baboons strapped to helmets and the student vivsectors in between smoking and dancing slam a 1,000kg hammer in to the side of the head. These same scum then seen laughing at the drooling, brain injured animal. Legitimate science? Its the thinking mans bloodsport, thats why all diseases are increasing. The use of animals is a crude science, fraudulent in fact and thats why diseases are not being cured.

  • You're right. I haven't seen those videos. I've never heard of those videos. If if such videos existed, what does that have to do with what's presented in this video? This is a legitimate form of scientific research and development on something that can make crippled lives better. Do yourself a favor. Type quadriplegic into the search bar and watch some videos about their lives, and tell me that the lack of

    aesthetics of a monkey in a lab is too much for you still.

  • Are you referring to quadriplegics born with no limbs as a result of animal tested drugs like thalidomide? It was animal testing that caused an awful lot of quadriplegia that you appear to be so concerned about. Opren, an arthritis medication, killed 61 people. Over 3500 cases of severe reactions have been documented. Opren had been tested on monkeys and other animals without problems yet killed hundreds of people. . Animal experiments are killing humans and thats why I say its a crude science.

  • Crude science? You got a better fucking idea moron? And what about the quadriplegics that were in accidents smartass, like 99.9% of quadriplegic cases are?

  • Yes Ive got a better idea you thick as two short planks twat, how about you start doing some research on the amount of human beings killed and made ill as a result of animal experiments? Stop playing with the emotions of disabled people by giving them false hope that their ailments will be cured by experimenting on fish, donkeys and the like. Ask the group Disabled Against Animal Research and Exploitation werher or not animal experiments work and see what they,the disabled people themselves, say

  • False hope. Sure, that's exactly what science is. False hope. Not like it hasn't drastically increased life expectancy or anything. Not like we haven't improved prosthetics recently. Not like there aren't already working prototypes for humans using these technologies. Listen you stupid son of a bitch, the world is a big fucking place. I'm sure you can find me plenty of unfortunate people who have hit the unlucky lottery. But you CANNOT DENY the benefits science has provided using these methods.

  • I said the USE OF ANIMALS to cure human ailments is false hope -not science- you uneducated dreg. Good science is great- like the discovery of penicillin which has increased life expectancy precisely because it WASNT tested on animals. If it had of been it would have been rejected as unsafe for humans. Why? Because it kills every animal the vivisectors tested it on. Animal research gives vulnerable people false hope, yet all the while human diseases increase. Go figure!

  • Okay. We both went mean and I'll admit I started it, so I really don't see any reason to keep insulting you when your intentions are good and, if you wish, you can extend the same privilege to me. Anyways, pretty much ALL of the shit in medical science was tested on animals first. It's difficult to find any medicine that didn't have animal trials first (not saying you can't find any). A lot of the newer prosthetics that work off of neural activity were based on these tests with monkeys first.

  • Truce accepted :-) Our argument is purely a professional one over the most effective way to cure human disease and both views benefit from civility. To continue then - I agree that nearly all medical drugs were tested on animals first (they have to be by law) and thats precisely why so many have gone on to kill humans or cause terrible side effects.Of the 200,000 medicines in the world, the World Health Org say only 200 odd are useful. Were going wrong somewhere and I believe its the methodology

  • @bosiex are you fucking serious...how about you go find out how many more humans would die if we didnt do animal testing and went straight to human testing. Those people did not die BECAUSE of animal testing, they died because animal testing failed. It seems like you are trying to argue that if didnt experiment on animals, less people would die, which is complete, 100% total, absolute, utter, bullshit.

  • He seems pretty happy with all that food.

  • So when can I pick up my Surrogate? I want one with all the features.

  • haha this was in that moive i thought it was fake when i saw the moive but wow its real

  • very smart

  • People who think this is animal cruelty (in suggesting so that it is not justified) can go start their own country. Call me cruel, as I will call you cruel for not caring about the millions of people this prospect will one day help and save. Humans #1. Human's pets #2. Wild beasts #3.

  • I agree it's not animal cruelty. But not based on the utility and benefit of the technology.

    Imagine being a monkey with a robot arm... That shit would be fucking cool. I'm OK with making a monkey feel cool.

  • @OfTheWillows best comment ever xD

  • Why is there something in the way of it's head?

  • I think it is like with his arms, so that he wouldn't do anything other than what it was suppossed to!

  • Comment removed

  • @stevenc123 I thinks its because they don't want to show the wires that are attached to the part of its brain that controls its right arm..

  • If monkeys cared about anything other than eating and mating, I would say this is cruel, but it honestly looks like its having a good time to me.

  • MMmmm marshmallows.

  • Yeah, but how can every amputee get a monkey? Its just not viable.

  • @ProjectWander

    Yeah well, I'm not sure if your comment was meant to be a joke, but it's clearly not for use on monkeys but on humans. The reason we use monkeys is because their brain and bodies act in a very similar way to our own, if you do a bit of research you'll find that chips have also already been installed in people who are paralysed so that they can use computers. Interesting technology and a huge step forward with regards to prosthetics.

  • @bizarrefruit yeah but if they put a monkey brain in a person, where does THEIR brain go? Again, can't be done.

  • @ProjectWander They wouldn't put a monkey brain into a human, they put the chip on the human brain as it's very similar, they've already done it... Interestingly enough the brain functions in a 'similar' way to a computer, it's just a series of connections that either fire or don't, similar to binary.

  • @bizarrefruit thank you mr. buzz kill

  • @MaxxPowerFTW Yeah, I'm sorry I bored you with all that knowledge and reason, allow me to write a reply that is more to your taste.

    ´dud, da munkey iz gunna tak ova da world'

  • @bizarrefruit you obviously missed the point of both PorojectWander's posts...he was kidding, but you come along "with reason" trying to argue with a troll.

    I wasn't saying thank you mr buzz kill because the "knowledge and reason" bored me...I was merely pointing out that there is no point arguing with someone when their intentions are purely based on comedy...

    l2troll

  • @MaxxPowerFTW Fair points, but, the sign to show sarcasm or a joking manner in text is (!), I didn´t see that present and you can hardly blame me for assuming that someone on youtube could be stupid enough to believe that, like you said ´L2troll´ right, just look at the comments below.

  • i don't know if this thing they do on the monkey is good or bad....

  • You didn't do very well in science while in high school, didn't you?

  • hey steve, it's probably not lethal because you have been choking on cock for a lifetime!!!

    but back to the topic of the video; if you want to have it tested on humans why don't you offer yourself? if you're so brave you can call everyone else a pussy, i mean it's not like you're using that brain a whole lot

  • give it a gun!

  • Aftr I read polyatheist comment I saw it the twisting motion the monkey doe with his right hand repeats everytime monkey is controling the arm it didn't have to be independent for amputise to use it

  • cool MONKEYBOT

  • you people should start wondering why they are doing this experiment....

    they are doing this because they wanna implant chips in our heads too!

  • I hope they do...

  • I'm waiting for the day.

  • They are doing it because it would be great for people who have lost their limbs to be able to have a robotic arm that worked just like a real one.

  • @NipponDanji2009 lol, this could be attached to a man missing an arm, his brain will completely control it as if it were his own arm.. The monkey is completely controling this arm with his brain alone! freaking incredible.. "The Brain that Changes Itself" Is where i first heard about this, check it out if you are interested in more..

  • hoax!!! i know some of you will thumb me down but it is fake..fake. fake,,,you think they did such a path breaking experiment and it didnt publish and was no where in news and was on youtube???? HA

  • Well, this is published in the journal Nature ! Nothing more than that ! You don't see it on TV because they prefer to show crap.

    Meel Velliste, Sagi Perel, M. Chance Spalding, Andrew S. Whitford and Andrew B. Schwartz,

    Cortical control of a prosthetic arm for self-feeding,

    Nature,doi:10.1038/nature06996­; Received 14 November 2007; Accepted 4 April 2008 (2008)

  • Thanks Gym...I got the point...

  • this kind of technology has been on tv, and its animal rights activists that would complain. when it came to testing products on animals such as makeup, you didn't hear about that until well after it has already been in progress. its not fake, the brain is electronic and works by sending signals with specific frequencies. we can easily track down what lobe our motor skills come from, and our brain, in time, can adapt to whatever is removed, or added to it

  • You need to pay attention to the news a lil more my young friend.

  • @mayanknawani Actually its a big breakthrough and it was published... Just because you can't find it doesn't mean it doesn't exist...

  • why is every1 complaining its just a fucken monkey!

  • yea if it was in the wild old snakey could of had its ass now that scientist are experimenting on it and it learn how to use i don't know some kinda robot power armor. The monkey can beat the shit out the snake so i think its good wot there doing.

  • there is no feeling in the brain people, the monkey is fine, just think of all of the gross diseases and things it would be exposed to in the wild.

  • As a potential beneficiary of this prosthetic arm technology i say fuck the god damn monkey.

  • MURDER!!!!!!!!!!! And after your fun session you killed this poor primate! How lovely what you did to his head! You should be the next!!!

  • @sophiadeluca Should we use your head instead?? I vote monkey over any human having to die... Don't be so close minded..

  • MURDER!!!!!!!!!! And after your fun session you killed this poor primate!!!!! How lovely what you did to his head!

  • @sophiadeluca ...*sigh*...you are an idiot...

  • That's fantastic, and a year old too.

  • they're not showing the monkey's complete head... guess why? how disgusting!

  • they ARE showing the monkey's head, genius.

  • i don't know what video are you watching... in this one you can't see the complete head, only the face of the monkey, and sometimes a wire. but you can't see how the wire is conected to his brain. it's filmed that way completely on purpose to make it less shocking.

  • or it's filmed so that people can ACTUALLY SEE a monkey eating with a robotic arm.

    The monkey turns its head around in instances and you can see a wire coming out of its ear.

  • Why?

  • @gmodfan11 The experiment was to see if by attaching electrodes to the part of it's brain that controls its right arm up to a robot, if the monkey would be able to move the robot arm with only its brain by thinking about what it would do with its right arm.

  • i bet the university is enjoying this (everything has a dark side)

  • @fuckedupsickfuckboy Actually your wrong, the monkey wants to use its left arm, if the monkey can use its left it won't try to move its right. The idea behind it is to move the RIGHT arm, so they restrain the left, that way it can only use the right arm. Why don't you do some research dude, you have google at your fingertips, stop sounding like an idiot... Educate yourself...

  • It seems in its brain the right hand is "connected" with the robotic arm. Whenever the monkey grabs the food, it turns the right hand clockwise shortly before the robotic "fingers" close. So it doesn't seem there to be a fifth "limb control center", but it's a reuse. Maybe with more training and time to let the brain "rewire" it can really be independent.
