Does the centre of mass of our bodies affect us in daily life?

I've been learning some physics for an exam, and come across centre of mass. Its where the mass of an object may be thought to be concntrated. So take a rectangular block, 2m by 1m by 1m, laying sideways like an oblong, moving towards you. It would hit you with most force if it hit you in the middle. If you got hit by the side, it would hurt less. I've also heard that professional martial artists manipulate their centre of mass, to give them an edge in fights. How do they do this? And if it really helps in fights, then does it affect us in daily life, for example, keeping balance, helping to lift something, helping to move something, and in sports? Just curious, any help appreciated, thanks. yeah i should have mentioned, I know about the line of action, and how moments are created and you fall if it goes outside of the base... so increase the width of the base and/or move more mass towards the bottoom.. but your body? is it just the stance you have?

1. When your center of mass moves outside of your base of support, you fall over.
