Sitting position: If you move back and forth, you "rock" but side to side is "swaying". What's the difference?

Actually, denotatively, swaying and rocking can occur in any direction. They are synonymous.\n\nAs you can see, many people assign various connotative meanings to the words depending on context, but still, swaying and rocking are synonyms.

Tilt your body weight to one side as far as possible and try to balance first.

u can tell. Unlike translating motion, rotation is NOT relative!!!\n\nThe simplest way to tell is that u will feel dizzy. there will be a centripetal force directing outward from the centre of rotation. this force will do sth to your biology causing u to feel nauseous

backwards-bending knees, but all else the same?  then the chairs would probably look the same, but would be wider to accomodate the shings bending back to rest on and slightly to the side of y'thighs... probably rendering arm-rests obsolete, as you'd just rest y'arms on y'shins.

The swaying motion while in deep thought [or in this case, in prayer and/or meditation] correlates to the rocking motion that mothers make to lull their babes to sleep and instill quietness, according to certain psychological studies made. Other faiths perform this same natural, 'rocking' motion including the likes of the Buddhist monks, Shintoists, shamans, etc. performing their mantras or other supplications while in deep meditative moods.\n\nFor the second part, I believe there are some passages in the Old Testament [either Leviticus or Deuteronomy, I'm not sure which] that mentions the importance of covering one's head in reverence to being in the presence of God, more often than not within the walls of the sacred temple or in front of the altar. It is quite possible that such a cultural tradition [emanating from the Jewish religion] has been handed down over the ages and into the modern Christian era which also has its roots from Judaism.\n\nPeace be with you!

Sounds to me like you are not moving enough.  If you are taking a beating you must be standing still.  Movement will free you of some of that.  But, post position is a physical posistion.  Expect some pushing and body checking.

My doctor told me to load up on calcium.  I also do sort of a yoga position.  It looks like that statue of Brittany Spears having her baby.  You're on your hands and knees with your arms forward.  It helps get into a comfortable position for a while.

The center of gravity will be different for different people depending on their height or weight or if the have their arm pointing forward or backward etc.  When you stand up from the sitting position all you are doing is changing where your center of gravity is to make it easier to stand.  Speed does not effect center of gravity however acceleration and deceleration does.

This happens to me, but I have a herniated disc in my lower back.  For those of you with healthy backs, if you are still getting pain get a more comfy chair, get up and move around more often and last but not least sit with good posture!!  Posture will not only make your back feel better but it makes you look more confident and presentable in public.

You need to see your physician. Sounds like a blood pressure issue and it is definitely not typical reaction to changing positions. Good luck!

Spread your knees apart while riding.....so it'll give u more balance. The motorcycle reacts to your body language. U going to fall to ur left shif ur weight to ur right...and the other way round. I started riding motorbike when i was 12 yrs old. ( illegally) and still riding legally.

tja... depends on which direction your hips bend - the knees are only one half of the equation! ;)\n\nAssuming your hips bend backwards, your butt would be in front of you, and this means a chair would look exactly the same way, becuase your knees would bend backwards. But the back of the chair would now be in front of you.

It may be due to all four casters not being firmly even.  Also, if the floor has any give to it (wooden floor in particular), that can cause it.  Finally, if the load is unbalanced, it will shake no matter how firmly it is sitting.  I had mine shake so bad that it moved across a concrete floor in the basement - finally traced it down to a small drip in the water line above, that made the linoleum floor below wet enough to allow it to move.

I know exactly what you mean.  My ankle does the same thing.  I can do it over and over again just by rolling it.  It is not like cracking your knuckles that you have to wait a while before you can do it again.  I do not know why it happens but it drives my wife crazy when I sit and do it.  I just wanted you to know that you are not the only one with that condition.
