How long can a live human hang upside down before dying; and what would be the cause of death?

It depends a lot on the condition of the human,and the method used to hang them. New research shows that you are at no more of a stroke risk hanging upside down than if you are exercising right side up. More in-depth research found that the body actually has mechanisms that prevent damage from hanging upside down. In fact, while oscillating (inverting with movement), some of the patients' blood pressure actually dropped a few points. (*Note: these studies were based on patients in generally good health. If your asking about a perfectly healthy human, I think they could survive for many hours between 45 and 72 hours. Cause of death would most likely be dehydration  assuming they are not offered a drink. Encephalitis (swelling of the brain) is also a high probability. Interesting question.

No, not at all. I've engaged in you-know-what on more occasions than I can count and it is fun, safe, and healthy. Some caveats:\nDo not do it while driving and this can lead to accidents. \nDo not do it while hanging upside down. \nDo not do it more than twice a day. \nIf you suffer from loneliness or depression, look for opportunities to do it with others. It can be a satisfying group activity, either with a same sex group or in mixed company.\nIf you ever get a you-know-what that last more than four hours--you should seek medical attention.

"the longest that humans can hold their breath for is about 2 1/2 minutes, and this is for pearl divers who make a living by holding their breath underwater. Most of us can only hold our breath for 1 minute."  (see Source)\n\nI think that there are extremes (world record holders) that are nowhere near the average.\n\nI read somewhere that there's a trick to holding your breath for a long time, and it is to eliminate the nitrogen from your body.  I forget how you do it (sorry), but the point was that it's the presence of nitrogen, not the absence of oxygen, that causes the FIRST problem for humans.

Try hanging upside down from the celing with some weights in your hand.

Not my area of expertise but I have heard that the human body can last a maximum of 120 years.\n\nJust like the Terminators batterys.\n\nI plan on living to 100...or more

Well.\n\nAs is said above, it depends on the damage caused, a shotgun or large caliber round is going to be pretty fatal, pretty quickly - three or four minutes of brain function (no consciousness) on the sunny side. Smaller rounds can leave repairable holes.\n\nIn theory, if he's got to a trauma team within a (at a rough guess) fifteen minutes and the injury is successfully repaired, he could continue living the rest of his life normally. HEMS in London have done this sort of operation in the field and successfully saved a number of lives. Normally though, the longer the delay between injury and surgical repair, the greater the degree of disability due to oxygen starvation of the brain. Even if they do survive that long they are almost certainly going to be unconscious, intubated and in ITU, which I guess may hurt your storyline.\n\nIn order to die after 20 hours, there must be a secondary cause - often multiple organ failure, where the various organs of the body (starting with the kidneys) shut down because they were deprived of oxygen whilst the heart wasn't pumping enough oxygenated blood. Other possibilities inlclude infection leading to septic shock.

There is no scientific proof that people lived this long, only biblical documetation.  Physically, the human body cannot live to that age at this time, or any previous time.  Maybe somewhere down the road.

theorically, I will live about 97 years, a normal good-excercised person on a normal country, will live about 89 years.\n<I will skip the scientific explanation.>\n\nthe answer should be: bones and organs decompose, it is totally imposible (at least now until 1000 years) that a person lives that much, heart and other muscular organs get old, and wasted, think about it.\n\n<altough I do this for free, 10 points as best answer wouldnt be bad>

yes. the fact that he is still on the ground means that some force is holding him down which would be gravitational force. if there was no graviatational force then he would be 'floating' in the air as if in outer space.

Darling don't dance around the question it was in you to ask it. Now be courageous and ask it. otherwise the collective wisdom of this forum won't really help. Now what do you want to know?\n\nI'll say that the expiration of life from this world does not terminate your existence.

no.I believe you will die at 100 years.Are you happy now???You should not think too much, or consult a doctor and find another work to do.Don't worry,be happy!

What the hell kinda question is that??? What would you want to do that for??? Well your answer is no, if you asperate it into your lungs, most likely your lungs will fill with fluid and you will die.

Not too much longer because the liquid that you intake does not have a way to dispose of itself therefore the fluid just builds up all over your body.  Slowly our body starts to shut down.  Its a very painful death.

It depends on the ‘speed’ of your spinning more than the direction. If you spin as close to the speed of light as you can, time will slow down considerably for you. So, yeah, in theory, you would prolong your lifespan.

this is an interesting question, because even if someone has a great diet and excercises and does not drink and smoke could die early and the opposite can live till 102...it really depends on the genes in this aspect and heredatary circumstances fall into place here too....but you can control it the best that you can..its hard to believe sometimes when you hear stories of people who chain smoke and drink all the time, never excercise and die in their 90's and on the contrary someone who does all the right things and dies of a massive stroke..just do the best you can and thinking positively and laugh alot, these are also factors to make you live longer..look at the all the comedians and conductors, they live a long time, i mean some of them dont look healthy, but they have what it takes..maybe its all psychological...

Depends on a lot of things like temperature, humidity, if bacteria/fungus capable of decomposing are present, how large the person is, when the last time they ate was, fat decomposes at different speeds then flesh and muscle and cause of death. Usually, for an unburied body 8-12 days.\n\nAlso you can have other animals (and plants) that will speed up the process. \n\nLots of insects can devourer a corpse in under a week but this may not fall under your definition of decomp. \n\nSome chemicals like strong highly concentrated acids and bases can liquefy a body in a couple of hours.\n\nFor micro organism decomposition (bacteria, fungi, excreta.) keeping the corpse warm and moist a corpse can be gone in 5-12 days above ground.\n\nIf the body is buried it takes longer to decompose, if it is contained (like in a coffin) it takes even longer. "Although an exposed human body in optimum conditions can be reduced to bone in 10 days, a body that is buried 1.2 m under the ground retains most of its tissue for a year" (quote from the web page I list as a source)\n\nIf the body is embalmed it may take a several months before it is mostly decomposed.\n\nReally this all comes down to when and how you consider a corpse decomposed.\n\nThere are many different stages of decomp. These not all stages are present in all cases, for instance you can have external decomp and internal together or just one at a time.\n\n*---*---*---*\nWarning- this part in may be gruesome:\n*---*---*---*\nAssuming a body left untouched, died of natural causes:\n\nPale skin will show up with in minutes of death because blood has stopped circulating.\n\nTypically the internal flesh of the large intestine will start first. Our intestine is littered with rotting/decaying organic matter all the time (poop) and our body is only able to stop the bacteria from rotting us when we are alive.\n\nWhen our digestive tract bursts it will release digestive enzymes that will digest our internal body most efficiently if our body is kept at living body temperature. This is where temperature can mean the difference in days and months of decomp. The body will release bile, which has a particularly awful smell. \n\nGas from bacteria make the corpse bloat up with hydrogen sulphide, methane, cadaverine and putrescine. Fat cells will liquefy and bacteria will thrive on them, the bacteria in our colon (large intestine) will have a field day. This is where the body will really start to stink.\n\nThe external flesh starts to decompose shortly after death this is because we have millions of bacteria on us all the time. Colonies of bacteria will form first in small circles in places that are the most moist and warm (mouth, arm pits, lungs). \n\nThe smell of the rotting corpse will attract Demetrius organisms like flies who will use their own vomit (actually regurgitate digestive enzymes) to assist in decomp with the purpose of making it easier for the fly to digest, and then they will lay eggs. When the larvae hatch it may be only a few days more until the corpse is simply bones, teeth, hair and finger/toe nails.\n\nOver time (many years) the bones will dry out, crack and crumble to become dust, and the corpse is no more.\n\nwww.deathonline.net lists the following stages of decomp.\nStages of Decompostion \nLiving\nInitial decay\nPutrefaction\nBlack putrefaction\nButyric fermentation\nDry decay\n\nwww.bbc.co.uk/health/ask_the_doctor/decompostionafterdeath.shtml states that "Decomposition in the air is twice as fast as when the body is under water and four times as fast as underground."

My hubby tells my son to hang upside down on a bar by his legs or swing from the bar using his arms for at least 3 minutes at a time.  Monkey like activities.....hope this helps
