Thanks, Bob. I agree wholeheartedly with your statement. I especially like the part when you say, “you'd BETTER be able to deal with these issues on your own ... because you've already eliminated the other option.” That is some rubber-meets-the-road no s--t. I like it.
Yes, the further a person gets away from their natural surroundings, the more mental energy is used up compensating for the increased stimuli. If 90% of the brain is working hard processing stimuli, even unconsciously, that only leaves 10% of the brain for problem solving. After time, if the brain only uses 30% of its capacity to process the environment, it now leaves 70% to problem solve. Eventually, diving, flying, extreme skiing, skateboarding, etc. becomes their natural environment, and problem solving increases ten fold.
In the spirit of the original thread though, I still am looking for some anecdotal evidence that diving in a relatively shallow, benign environment will get you killed. Panicked, perhaps. Swimming to the top when unnecessary, probably. But has anyone really died on a shallow dive? And if so, enough people to warrant such vilification on those who even ask about it?
Thanks again for the feedback. I’ll let it go, and read the posts.
