Last sunday, I was in church and for some strange reason, I started observing people. During the part of the mass where people were meant to stand, no one could stand perfectly still.
What I found funny was the range of movements people made while they were suppose to be standing upright (swaying, near dancing e.t.c).
My bro claims that the guards at Buckingham palace can stand "perfectly" still. A friend claims that they use a special technique (something about their calves) to remain still.
As far as I know, death is the only way to remain perfectly still (obviously not standing).
Why is this? Can anyone stand perfectly still? If they can, how long can they stand perfectly still before they begin to sway?
