why we stand and walk on our legs insted of other part of the body?

we used to walk on all fours (we were quadrapeds), but we evolved to use our thumbs. the reason is that we use our thumbs for work, not movement

to balance your walk.

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.

They make their legs more aerodynamic.

When a person walks slowly, very slowly, the upper limbs tend to swing in unison. Basically, what is happening here is that limbs swing forward to catch up with the forward movement of the body. Because the body is moving slowly, the limbs are actually moving faster than the body (that is because the limbs are accelerating through the force of gravity). When the limbs move ahead of the body, they have to swing back. So, the two limbs are moving back and forth like a pendulum. When a person walks at a medium to brisk pace, they tend to swing the upper limbs in a contralateral fashion with the lower limbs � that is right foot and left hand move together, while left foot and right hand move together. There are some experts that will tell you that this movement is being done for the purposes of balance, but I find that explanation to be unsatisfactory at walking speeds (it works a little better for running, but running is a completely different style of locomotion than walking). We can, after all, walk just fine without swinging our limbs, such as when we are carrying and object or when we make a conscious choice not to swing them. Similarly, when we carry an object in only one arm, the other arm tends to swing. One swinging limb would actually be harmful to balance, so in my opinion if arm swinging is important for balance during locomotion, you wouldn抰 swing your arms unless you could swing both of them. What I believe is happening is that arm swinging is a neurological holdover from quadrupedal locomotor patterns. When quadrupeds walk, most of them tend to do so with a contralateral gait pattern � which does aid their balance when moving at slow walking speeds. Human bipedalism is such a new evolutionary development, that the neural pathways that control locomotion have not yet faced selective pressures to change. So, when we swing our arms, our brain (or perhaps more appropriately the cerebellum) is controlling our limbs as if we where still quadrupedal animals.

because we have prettier feet? lol

the reason flamingos stand on one leg is so if a predator attacks that one leg it switches legs making both legs not vulnerable at the same time. they are born with this instinct and very good balance and equilibrium.

You are referring to an OBE, Out of Body Experience. We travel without true physical form, carrying with us the appearance of ourselves which is linked back to our body through the "silver chord" a type of spiritual umbilical chord. Normal physical limitations do not exist and we can pass through objects that normally would be solid.

I think it is because you don't have the grip on your feet like you do on the bottom of most shoes. Plus you get added protection when you drive.\n\nI had a friend in an accident I assure you if she had been driving sans shoes, she would be an amputee today. Her boots protected her ankles even though she broke it, imagine what would have happened without shoes.

In most people the right leg is dominantand is stronger. Therefore it is impossible for anyone to run or even walk in a straight line for any extended period of time. Often people lost in the desert end up walking in circles because they have no land marks to aim for. We always tend to turn to the weak leg.

Who cares? Our lives are better than yours.\nHave you not seen a person be healed? It happens all the time, people's legs that were cut off grow back!!! Can science explain that?

The area of the leg behind the knees, (not inside the joint, i.e. the part you can touch from the outside) is called the "popliteal" region or area.

Because we have muscles on both sides of our fingers - or rather, tendons.  Our legs and our arms are the same way.  In order to extend our fingers or to clench our fingers, we have to use opposite muscles in order to do so.  When we relax BOTH sets of muscles, we end up in the middle, and hence, our fingers take on a curved look.

*circulation problem\n*fungus among us\n*slight scoliosis, back problems, or one leg longer than the other, causing a different amount of pressure on both feet while walking.\n*see a dr. if your concerned

Pain that is caused by another part of your body having a problem that is felt somewhere else.\n\nExample... pain in the back of your leg can actually be orginating from your low back or hip.

It is actually common that one arm is a different size than the other.  Body builders have this problem often and is one of the reasons they are graded on symmetry.  Any cardivascular excersize especially dancing works the largest muscles in the body which are the legs.  This releases hormones that promote muscle growth.  So you are probably predisposed to this genetically.  Especially if you are right handed.

Its just simple muscle memory and endurance. You will be better off if you either use your left hand while jumping off your right leg, or your right hand when jumping off your left leg. It may be awkward to begin with, but it will definetly help you out in the long run.
