Slack line

After a few minutes of learning how to walk on a slack line I noticed
something kinda strange. Walking along balancing, I sometimes stick
one leg out just to the side of line, so I'm only standing on one leg,
kinda precarious, but it helps. Seem that when I'm starting to fall
to one side and shifting me arms to one side is not enough my body
knows that sticking my leg out will help. But my head does know what
is going on.
