Why do you get the sensation to jump when you are high in the air??

If you like heights like me its normal. That means your an adrenaline junkie. When you looking down from a high place you want to know what it feels like to fly and just be free.

A simple was to state it: The sensation that you react to, like a pinprick, or sudden shortening of your tendon (like when you slip) sends a message along the sensory axon.  This communicates with a motorneuron in your spinal cord, which immediately sends a signal to a muscle-so that you jerk your hand back from pain, or move your leg to catch yourself before you fall.  The whole sequence doesnt involve your brain at all, its all done in your spinal cord- a single synapse.

It is a fear of heights (top of a building, climbing a tree, for some flying, etc).\n\nFear of heights: An abnormal and persistent fear of heights. Sufferers experience severe anxiety even though they realize as a rule that heights pose no real threat to them. \n\n**Fear of heights is termed acrophobia. The word "acrophobia" is derived from the Greek "acron" (height) and "phobos" (fear).

If you mean why does it feel as if your heart is beating in your head or hand or foot, etc?  Well sometimes when your blood pressure changes the added intensity of flow will cause your extremity to "beat" but it is just your blood moving through your arteries and each "beat" is a surge of blood.  It happens when you have been exercising, get excited, have a sudden bust of adrenaline or even if your circulation was temporarily cut off and it has recently been restarted (like when you sit on your foot or cross your legs).\n\n\nIts nothing to worry about unless it happens a lot.  If it happens often you could have hypertension and should ask your doctor about it.

Because you are moving fast too. It's the same reason you can jump on a train and land in the same spot.

Depends on whether the lift has reached its maximum velocity and how good a jumper you are. While the lift is accelerating down, your weight is reduced and hence you would need less jumping energy to jump up to the roof. So your chances of hitting the roof are higher...again, no guarantees since it depends on the lift's acceleration and your jumping ability.

it is an adrenaline rush, you start to think about everything you did that got you to this point and it gives you a sense of relief. the first time you step out to play you feel the nerves but you know you belong once the game starts. and then when you actually make a play it is just WOW and life goes on.

What makes you so High and Mighty??

Hold your breath while spining around until dizzy. This duplicates most of the qualities of being high, giggling, euphoria, dizziness, and no long term health effects.

The best advice I ever read on this was "...to jump higher, you need to jump more". \n\nSimply stated, he was saying that the muscles that give you lift when you leap are best developed by repeated use.  Select something at your home that's just a bit too high for you to leap and touch (like a tree limb or a high ceiling).  Then try to jump and touch it 20-30 times per day.  When you finally do reach it, move on to something higher.  \n\nKids who are addicted to basketball LIVE for that first dunk.  It usually comes around age 16-18 unless they're truly gifted (AND tall).  You'll see them on the schoolyard trying to dunk, convert alley-oop passes, and sky for rebounds, for hours at a time...every day.\n\nPractice, practice and MORE practice.

I think It's all in the way you move your head honestly turn your head and arms in one direction and the rest of your body will follow but you are right if you do it before you launch it can make you lose some air just cause your body is reacting to to much to soon and try to think about the landing afterwards not just the spin  and of course experiment with how your body reacts to diferent moves until it becomes fluid---well good luck---

It means that your ateries and your veins are squeezed, and so they are slowed down by the pressure you are holding up in your legs. so then you feel a tingly feeling because your blood is now flowing and is easier for the blood to flow.
