What would happen if we walk on our hands not legs?

If its a matter of just some people then nothing may happen.But if everyone start to behave that way,then possibly in a long time the hands may change shape ,and so would legs,,becuase nothing in nature is "just like that".Everything has its own function and meaning.So not just the hands and legs would change positions but also ,thoughts,brains,habits,and almost everything in humanity could change.maybe we humans would call ourselves by a different name then.Earth would be downside up ;).\n(in medical terms this is an anomaly if it happens,and may be due to mutations of some kind,,,only similar and repeated mutations can change the course of life)

You're probably not wearing socks.

It would be nice if I had 4 arms and 4 hands. But to anser your question..... NO!

it is better to handle things with hands rather than feet

Could you feel small, scurrying feet?

what would happen to the person i think its a more important question.. \n\nthe capilaries would swell up big time, and you would be sweating like a fountain.. but I dont think you would be able to stand there for long

no, 10 fingers on each hand to ease typing and using various hand-held devices. and no toes or legs for that matter - everybody will be floating around on antigrav pads, grafted in at birth.

You could have your feet above your head which makes blood go to your head/heart faster.  Also if you're wiggling your toes, the blood will flow even faster to the lowest point (your head).

Assuming I'm basically continuing as an upright-ambulating critter.... ?   Rather have a nice flexible tail, which might double as a separate grasping "hand" on occasion.  Although I can't imagine a tail that would handle my bulk, because of being "built for comfort, not for speed"....but it could be a fashion statement....  \n\nCan't see where I might need that much flexibility in my feet---the way I balance, FORGET standing one-legged and bringing up the extra foot-hand....!\n\nToo bad your question option didn't include "an additional, and separately functioning brain" versus "two additional, functional arms and hands".  (grin)  I'll take BOTH of those, ty very much

According to a column that I read written by Joël Carbonnel, "Nature has never been able to count above five."\n\nA researcher has discovered that when the limbs have more than five digits they become distorted into a bow-legged shape which seriously interferes with normal walking or running.\n\nhttp://www.positivehealth.com/permit/Articles/Regular/joel74.htm

Dr d is right, everything depends on the environment and our own selection choices, however s/he is wrong to say these cannot be predicted.\n\nOne can predict that we will live less active lives and will have less requirement for fitness, altough that is not to say that fitness traits will be lost.  There is absolutely no reason for us to go bals or lose fingers if there is no selection for them.\n\nIf man stopped using his little finger (pinky) it would not be lost this is because change only occurs when there is pressure for it to do so.  Man would be no less 'fit' with or without the fifth finger so it would remain, unless men and women decied it was sexy to have four fingers and only individuals with smaller fifth fingers ever bred.  This would cause a shift towards fewer digits, but come on, this would not happen.  \n\nOther answers are correct for saying that our diets and environmental conditions may affect our health and body weight.  For example diabetes is becoming more prevalent in the USA so we might expect natural cases of diabetes to increase, but in 2000yrs it is likely this will have been addressed.

Your legs will be very tired. But make sure not to do it at night when the sun's not there...

You can cut off blood circulation in your feet, or you can have sores develope.  Once your feet hurt bad enough your body will attempt to keep you from walking by making your knees buckle.  So just buy some new shoes, or go barefoot!

Man, of course! In King Oedipus (Sophokles), the same question is asked by the Sphynx. You have 4 legs when you are a baby (you can't walk, it's the morning of your life), then you walk on 2 legs later on, and when you are old, your third leg is the stick you lean on.

Otherwise certain internal organs and networks within the body would not be able to function.  For example, the joints between your vertebrae can move only slightly.  They move enough so that they can absorb impact, but if they were more flexible in their range of movements, not only would they not be able to protect your spine, they would actually damage it.  Another example, if your knee joint were a ball and socket one, the muscles, tendons, ligaments, nerves and blood vessels would become tangled and cease to function, essentially shutting down your foot as a functional appendage.

it depends on the damage to the left hemisphere. if the damage is extensive, the person would lose right side motor movement, meaning they cant really control their right arm and leg. their language will be impaired, and the right hemisphere will take over the laguage. \nif the left side is not extensively damaged, then the person will not really lose motor movement, but when they walk or grab things with their right side, it will look awkward. the language will be impaired, as with reading and writing and speaking. the left side can still control the language section, but with help from the right hemisphere

i would say, based on the human body being symetrical, if we only had one hand, it would have to be in the middle of our chest. that could be dangerous i think.
