Why do both the eyes move when I try  to move one,whereas hands&legs dont ....!?

The areas in the brain that control the eye muscles send the signals to both eyes at the same time.  This is called muscle yoking.  It helps you look at objects at different distances and track objects that move across your vision.  The muscles in your hands/legs are activated separately from each other.

It could be that that particular eye is dry, sometimes when our eyes or one eye is dry the body compensates by sending more water to the dry part of the body thus causing it to water.  Try seeing your doctor to make sure nothing out of the ordinary is going on inside of you.\n\n\nHope this helps

This happens for the same reason that your nuts drop when it's hot, or shrivel when it's cold. The guy who said "temperature regulation" is right.\n\nIt only looks like one is moving because humans aren't perfectly symmetrical. If you notice, one of your balls is bigger than the other and hangs lower than the other; one of your ears is higher than the other; one eye is slightly larger than the other; one foot longer than the other. It's for this reason that this optical illusion happens when you see your ball moving up and down what you check out yer sack. Chances are you're noticing the one that hangs a little lower, and it's just doin' it's thing - keeping the right temperature: not too hot and not too cold. Gotta keep the porrage "just right". Ya know?\n\nSo, that said, it's no big deal unless it starts dancing or talking to ya, man. \n\nSeriously, it's normal.

Your eyes move depending on your thought process.  They say that you can tell if a person is lying by looking at their eyes.  If they look up its a lie, if they look down its the truth.  there are other things like this.  It is a subconcious movement of they eye.  George Carlin said that ehn he thinks about the past he always envisions it somewhere off to the left.  Its like the part of a book that you have already read.

you need to go to a doctor.  double vision could be a bad symptom of something.

Its due to the inability of the brain to control motor neurons and where it is sending the electrical impulses; also it can act like a short circuit where you say blink an eye, but signals fire muscles not only your eye but also in your neck which cause involuntary movement... we all take it for granted... you only notice this balance when something goes wrong..... I think for some conditions it can be very painful... just imagine how annoying that would be to you... these people deserve a lot of respect for what they have to put up with, not only the condition but the attitudes of people towards them.\n\n\nps: there are better ways to word that type of question... perhaps you could have used mentally handicap... to be retarded refers to being held back... and I dont think that is the case these days as most conditions are better understood.

I suspect it's something simple.  I think because of the way your arm joints work, when you release the board with your right hand, for example, the board will have a very slight horizontal inclination to the left, which will eventually cause it to turn in the air and veer to the left.\n\nIt will be interesting to hear what someone with a knowledge of biology or physics will say though.  :)

Sounds to me like you have a  mental block. We all have different strenghts and weaknesses. I know I am horrible at math, but I kick butt in astronomy/cosmology and I read very, very fast. Also I can't draw worth a damn but I've won awards for my writing. Also, I am very good with problem solving and logicl problems. By the way I'm right handed.\n\nTo see different things that the left/right brain affect/control check out: \nhttp://www.viewzone.com/bicam.html\n\nhttp://www.funderstanding.com/right_left_brain.cfm\n\nhttp://brain.web-us.com/brain/LRBrain.html this one lets you take a test to see if your left or right side dominant

My mother says that when I came home from kindergarten one day, I proudly told her what I had learned that day.  Holding up my right hand, I said, "This is my right hand," and holding up my left hand, I said, "And this is my wrong hand."\n\nThey made me learn to use my right hand instead of my left from an early age.  But I still use my left hand if that is what is convenient, and although I never learned to write with my left hand, I can do it [not as well as with the right].\n\nWhen playing pool, this comes in handy, as some shots require contortions if you only use the one hand, so I switch as needed.  Hammering and screwdrivering are also better in some positions with the left hand.  I also tend to cut things on my plate with the right hand, holding the meat or whatever with the left, then put the food in my mouth with the left.\n\nI know a few people who are so right-dominated that they might as well not even have a left hand, it's so useless to them.\n\nIn fact, I have two friends, one righthanded and on lefthanded.  I explained to each of them [separately] about my use of the mouse, which is as follows: it is on the left,  and I use the left hand, but I don't have Windows switch the buttons.  I explain that the left mouse button is still on the left and the right button is on the right regardless of what hand you use to push them.  But they can't understand this and can't use the mouse unless, for the righty, she moves the mouse or changes the buttons, and for the lefty, she changes the buttons.  They can't left click with the left hand, even when they are lefthanded....

It's called saccations when your eyes jump. Saccations are short leaps across the words. This happens because your eyes can recognize words faster than your brain interprets them. I do the same thing (lose my place) sometimes, but it's normal. It has connections with speed reading. We studied this in one of my classes last semester.

Because when eye muscles relax, that is the natural position....When tired and falling asleep, you relax and the muscles follow.

It's about balance. Try to imagine your weight centered exactly between your two hands. Try to arc your palms, too.

It's due to the way in which your eyes percieve light. Focus is determined by a point of reference. If your friend that you are looking at is the point of reference, they will appear as if they are not moving.\n\nThis is similar to when it looks, in a car, as if you are going backwards when the truck next to you starts moving forward.

I believe its because the structure of their leg bones is an example of the ball & socket joint. Therefore it allows them to move the joint on the socket in one direction like sideways. Sorry if it's hard to understand or imagine.

It is normaly associated with either drug use, or brain damage, no offence intended. But if you were born that way, it might be normal, just genetic blueprint glitch. You most probably have one leg longer than the other too. Most people do.
