My first near-death experience was an accident, a botched anesthesia during a triple bypass. I had listened to several people on TV talk shows who had gone down the blue tunnel to the Pearly Gates, and even beyond the Pearly Gates, or so they said, and then come back to life again. But I certainly wouldn't have set out on such a risky expedition on purpose, without first having survived one ...
To go through the Pearly Gates, no matter how tempting the interviewee on the other side, as I myself discovered the hard way, is to run the risk that crotchety Saint Peter, depending on his mood, may never let you out again. Think of how heartbroken your friends and relatives would be if, by going through the Pearly Gates to talk to Napoleon, say, you in effect committed suicide.
