Thought so. This assertion was made by a "researcher" in the journal of the Society For Psychical Research, one Susan Blackmore, in 1983, following a postal survey (yeah, right!).

But she changed her mind about all this rubbish, stating in 2000:

It was just over thirty years ago that I had the dramatic out-of-body experience that convinced me of the reality of psychic phenomena and launched me on a crusade to show those closed-minded scientists that consciousness could reach beyond the body and that death was not the end. Just a few years of careful experiments changed all that. I found no psychic phenomena - only wishful thinking, self-deception, experimental error and, occasionally, fraud. I became a sceptic.

There ya go. The only out-of-body experience you'll ever have is going for a dump. You show that turd who's boss!

Susan is married to the estimable Adam Hart-Davis, by the way. That don't mean a thing, I know that.
