From cobbled streets to Atlantis

Sorry, I was making a light comment not intended as an insult or judgment (positive or negative) on you personally...or anyone else, for that matter. I think that was pretty obvious. Given the subject, it's rather silly to get so offended.

However, there's more to the situation you posited than simply living in isolation. Eating mushrooms and drinking "virgin" water isn't enough to sustain human life in the long run, the psychological issue of monotony aside. People also require some degree of medical care, there are various hygiene issues, and so on. If, for example, you fell and broke a leg, or suffered some other kind of serious injury or illness, continuing to live -- or to try to live -- in isolation, with virtually no resources and absolutely no help, might not be the most pleasant existence. There are also the inevitable mental and emotional issues that will crop up -- not merely loneliness, but lack of true or sustainable mental stimulation and involvement with more than one's tiny immediate world.

Point is, no matter how well you may think you can live in the kind of very real, total, absolute isolation you describe, the fact is no one can know what such an existence is really like without living it. Perhaps you've lived in some form of isolation, but it's highly unlikely it was anything like the hypothetical existence you describe here, and in any case you're not living that way now if you're on the internet, so you could (and did) escape from such an existence.

Anyway, you may believe you could live in such a way, and maybe you could. Since I indeed don't know you, I couldn't say definitively...though I can fairly say I think the odds are heavily against leading the blissful existence you describe. On the other hand, you could as easily be kidding yourself about how readily you could spend the rest of your life that way. Self-delusion is a common human trait to which we all succumb to some degree, at one time or another, though usually over minor things.

However, this entire discussion is, if nothing else, moot -- since the center of the Earth isn't exactly the way it's depicted in this movie. So this whole exchange is pretty pointless.
