The reason why is because when the heart pumps all that blood, it has to go somewhere. So it goes through your legs and arms and stays there I guess. So when you go upside down, the blood will go down and eventually go down into your brain. That's why it isn't good for someone to stay upside down for a long period of time.

When flying south why dont you go upside down?
Birds and other animals that fly south during migration follow natural navigational cues such as the sun, stars, and landmarks. They do not need to go upside down because their internal compasses and instinctual behaviors guide them in the right direction. Additionally, flying upside down may not be aerodynamically efficient and could pose risks to their safety.
Why can't helicopters fly upside down?
Actually, a helicopter can fly upside down but not for long.If you go to... http://www.guardian.co.UK/notesandqueries/query/0,,-186989,00.htmlYou can get answer to why I say they can fly upside down. They can only fly upside down for a certain amount of time though.My reference is ^. I am NOT playgerizing.The reason is due to the design of the rotor blades and the grips that hold them and the mast. It is how the parts were designed to carry loads. Most Mast and Blade designs are build to carry a load UNDER it but it is not rigid enough to invert it so the load is above it.Most vintage Bell Helicotpers had teetering rotors and was limited to about 60 degree banks because the rotor blade would bang against the mast. In the 1980's they had some accidents involving "mast bumping" and they had to redesign the rotor system to include bumper pads or stiff springs to absorb the shock of the blade hitting the mast.However, most times that helicopters are flown upside-down they are flying such that the G-forces is still loading the rotor blades in the same direction. They can do a Loop or a Split-S and the momemtum of the helicopter keeps the rotor blades loaded in a positive force. They very seldom fly inverted in level flight so the load on the rotor is Negative.

Is that true if you put your head upside down you'll get smarter?
its actually not about you get smart or not and im not really sure about that. what im sure about is that if you put your head up side down, the blood is going to change it dircation which is good for the brain as well as all the head. So the summery of that is if you put your head up side down the blood going to go to the other part of your head which is the uper part. The proof for that is when you put you head up side down for 2mint and return it back you ging to relase there is some thing comeing down inside your head which is the blood that went up and come back and these is really naturle... hope its going to helpe :)
