  1. I know Lucrum will appreciate this. And I wonder how many trading opportunities we miss because of it.

    Copied text from an email, and the accompanying link below:

    The link below takes you to a great illustration of what we were taught about scanning outside the cockpit when I went through training back in the '50s. We were told to scan the horizon for a short distance, stop momentarily, and repeat the process. I can remember being told why this was the most effective technique to locate other aircraft. It was emphasized repeatedly to not fix your gaze for more than a couple of seconds on any single object. The instructors, some of whom were WWII veterans with years of experience, instructed us to continually "keep our eyes moving and our head on a swivel" because this was the best way to survive, not only in combat, but from peacetime hazards (like a midair collision) as well.



    We basically had to take the advice on faith (until we could experience for ourselves) because the technology to demonstrate it didn't exist at that time.

    strange what will work... Special Forces people [and Aboriginals and who knows who else] can uproot a plant and hide behind it, moving slowly over a long period of time towards a sentry until they are close enough to attack with a silent weapon.. or even go right on past the line of defense, entering and egressing undetected.

    The eyes only see details in a very narrow 3 degrees off from straight out, the rest of the field of view is filled in by what is essentially the imagination... if things change outside of that very narrow field of view of the central vision they can go undetected.. if things change slowly enough they can go undetected..

    Martial artists have a particularly intense problem. If they blink an opponent has a half second to initiate an attack, if they stare they might not see something start that is not in their central vision. People want to fight sometimes, more than once I've had people squaring off on me, I locked eyes with them, put up my dukes like I was going to box and then round house kicked them in the ribs/spleen.. they always said something like "that was quick!!". It wasn't particularly quick, I just set their imagination up to think they were going to get punched in the face and attacked from an area that their central vision could not detect and they were no more able to discern it accurately than if I was standing behind them...
