>>Are our PSK's an attempt to control our lives to the smallest detail, even the times of our lives that we don't plan on happening, but we want to control in the event they do?<<
I don't think they can be that.
I think a true "control freak" would never acknowledge the component of the "unknown" in the future by explicitly preparing for it, could not accept the possibility, or the inevitability, of the unexpected. By the minimal preparation of the PSK, we're embracing the reality of the "unknown", and preparing for it... an open acknowledgement that we may NOT be in control. When the Tom Hanks character was (by your analysis) a "control freak", he did not prepare- it would have been out of character.
Some would even claim that the PSKs are evidence that we fear the future. There might be a grain of truth in that, but I prefer to think of it as just wanting to see as much of it as possible. <img src="images/graemlins/wink.gif" alt="" />
