If we were meant to walk upright, why do we have to think about it in order to do it?

You have the question backwards. The vast majority of animals can not sleep standing up. An inability to sleep standing up is the default trait, it is the primitive condition. Therefore the real question is why was an ability to sleep while standing selected.\n\nOur earliest ancestors were cold blooded and couldn’t move at night anyway, so obviously it made no difference whether they slept lying down, standing up or hanging form their tails.\n\nOur first warm blooded ancestors were nocturnal and lived in burrows and hollow logs. In those conditions it makes no difference whether an animals sleeps standing up or lying down. \n\nOur first primate ancestors were arboreal and either slept in dreys, in hollow branches or hugging the branch of a tree. Under those conditions it would be positively dangerous to sleep standing up.\n\nOur first ape ancestors either retained the trait of sleeping hugging tree baches, or they built nests on the ground. Once again it would be positively dangerous to draw attention to yourself by sleeping standing up.\n\nOur first hominid ancestors presumably built nests on the ground. Once again, the idea of standing upright in the middle of a savanna while asleep is pure suicide.\n\nI really can’t see why you believe it was ever beneficial in our evolutionary history to sleep standing upright. What possible advantage could it give to draw attention to a helpless sleeping animal by having it stand up?\n\n\n>>>>In a prehistoric world would we not have been more at a disadvantage for sleeping while down..\n\nCan you explain how we could possibly be at any disadvantage for sleeping in a position that minimises our visibility to predators?\n\n>>>>or sleeping for that matter.\n\nWell if you are asking why animals sleep at all that is an entirely different question with completely different (and less certain) answers.\n\nIf we accept that animals do need to sleep then I can't understand why you think standing out against the background would be beneficial.

because they think with there feet

There are many things that we do that do not require our conscious brain.  Whatever things you are talking about, perhaps the subconscious got started on it before the consciousness got involved.  When cockroaches feel stimulus on their back legs, they begin running before their conscious mind knows why they are running.  It's just like the other poster said, the impulse telling your hand to pull oout of a fire doesn't require your conscious mind to make a decision, it starts the process for you.\n\nIt's an interesting idea that this might have to do with quantum wierdness, but I think experiments woudl reject that.  I encourage you to keep thinking of things like this and hypothesizing.  Eventually you may be teaching us instead of the other way around :-)

If you want to get somewhere no matter the distance it always starts with taking the first step. As baby when you want to learn how to walk you always fall down when you take 1st step and you all ways try to take walk regard less of falling down so some how the other you have fall down and you have to start trying it. And that’s how you will learn some thing in your life.

to help us move; so our movements are smooth. So the bones won't go grinding against each other

we were born with will.  the will to do whatever comes into our minds.  when we choose to do something, that choice is accompanied by consequences - good or bad.  If the choices you've made are resulting in negative consequences - simply choose again, but choose differently.  The reason things happen is because you consciously, or subconsciously, do things to make them happen.

it is really all about coservation of angular momentum.  If we didn't swing our arms then we would have to do more work to rotate our entire bodies back and forth.\n\n^^

I think we, as humans with limited brain capacity, have to think of things in terms that we can understand. Instead of space being this infinite area, we put a shape to it, a circle.\n\nMy thought is that space truly goes on forever, and does not have a true shape.

Maybe if you didn't keep turning the wheel over to a non-existent being, there would be less accidents.\n\nI'm on my own plan.  I guess it must be the "flesh" plan if you must boil everything down to your simplistic choices.

Why not try to run instead of walking?

think about it...your asking why you wonder why you wonder? thats like asking why you think why you think...or quite simply! why do we question our ability to question...\njus put it this way...god gave us minds to question the world...yet you could point out that some religions believe that god intended us to act in a certain way...so why give us the subjective capability to think subjectively?\nextend you thinking process and wonder why god wondered why it would be beneficial for us to ask why and then ask why we ask why and reflect on why we ask why and think why why is being asked?  furthermore, why do we ask why we ask why when essentially we acknowledge to ask why in the first place!\nhmmm

Tough question. To me, living is inseparable from thinking! I cannot live without thinking, even when I don't need to. But I simply can't do with it :). People sometimes tell me I think too much. But I see it as a compliment :P. U know your question reminds me of this which I read somewhere.. "Thinking is hardwork, maybe that's why so few people engage in it" :-)). All that thinking does wear me down no doubt.

Try to think harder and try to remember where you put it.

Gravity.\n\nAlso you have changed the terms of the original proposition.\nIn addition to simply going from point A to B and back, you have added LIFTING (applying additional force) to go UP the stairs. Going down the stairs your legs support your weight, as they always do (subject to a bit more force, perhaps), but when you go UP the stairs, your muscles have to raise your body weight, and pull it up.

Because when a person steps forward, their stride is longer from years of experience and balance.  When you try to step back, you are stepping blindly...(unless you have eyes in the back of your head) or turn your head around.  The body is more cautious stepping back for saftey reasons, therefore, the steps in reverse are smaller.  As a result it takes more smaller steps to undo less larger steps.  It is usually more difficult to undo things than it is to do them...Take the toothpase analogy for example...it's easier to squeeze it out than to put it back in the tube.
