I’ll bite: what does balance mean?

I'm sure there's a scientific definition which I don't know at this moment. But just in layman's terms: I think balance is the most efficient way of positioning your body relative to the earth's gravitational pull.
An example of being in and out of balance in pool would be: If you evenly distribute your weight between both legs and then bend over towards the table to get in position to shoot, you've got an uneven distribution of weight leaning forward that need to be countered. The counter that would put your body in balance would be to lean the bottom half of your body back with the top half leaning forward. But it also depends on the position of both feet as well, so it's not something that can be generalized.
Being out of balance will make you work harder and tire sooner.
