Has anyone ever been able to prove that they have had an out of body experience?

Yes, in a past study conducted by a well known university and 2000 medical cases of persons that were medically deceased for moments or minutes and revived, so as to have died and then fully recover, there were many that had similar experiences but out of the 2000 only one person was able to prove that they were on another plane looking at their own deceased body and the doctors activities and the dialog, and this person was able to correctly identify the attending physician, the moment of death, the position of certain people and where he was as he was experiencing the moments afterwards as though he were a third party observer as well as what was said at that time, without any doubt.

Here is my previous accounting of the same:

From a very recent university study on 2000 people who were declared medically dead (heart, brain, breathing, blood oxygen and pressure) and who were revived after a certain amount of time, revealed that over 50% experienced a sense of overwhelming fear. Mental anguish is certainly concurred as a state of pain and with that many people under scientific and laboratory research conditions thereby conclusively proving the certainty of some relevant pain. One interesting finding from the study was that only 1 person from all those studied had a verifiable out-of-body experience where he was able to identify and observe and recall events following his death from a third person perspective which can be considered a form of remote viewing. This occurrence lasted for minutes and was verified by other persons present that what was recalled was an authentic observation of the after death life form.

Depends what you mean. Psychedelic drugs can produce such sensations at times. It really just seems to be certain brain areas making connections they don't normally make. It's really fascinating what mere micrograms of a drug like LSD can do to your entire perceptual experience.

As for NDEs, I've yet to find anything that's conclusive for it. Problem is you didn't actually die. The case mentioned in the only other reply (as of this post) is still a case of very near death but not fully dead. The machines could have been wrong. Mistakes could have been made. It happens all the time for much less notable occurrences. The thing is the events described still situate that person in that space to be able to have had physical access via sensory input to the data reported when they were ‘out of body.' Death still isn't a solid definite thing even if all our tests declare it has happened. What is certain is that after a point of necrosis the person isn't coming back, ever. We may be able to push this along ever more slightly but we're talking minutes and seconds here. This is why we have so many ancient resurrection myths. It's a fantastical phenomenon because it doesn't happen.

Does failed entrepreneurship weaken the application of an international MBA student for US B-schools?

The typical US mindset is to "appreciate entrepreneurship" and "give second chances" even to those who have had to "file for bankruptcy" because of market conditions...IF your entrepreneurship attempt is put forth 'logically & sincerely' - the chances are that your application could end up nearer the "top of the pile" of other

If Africa had been completely ignored during the era of European Colonisation, where would it be today?

How far back are you referring to? The Egyptian Empire in Africa would be pretty hard to ignore whether 3,000–12,000 years ago, let alone the contemporary seagoing empire in what's now Ethiopia that was trading with India, let alone Central Asia, thousands
