Balance becomes measurably more valuable as you age. When you are young it is easier – even advantageous – to spin wildly beyond the reach of balance. It is exciting to feel the pull of assorted centers of gravity and if you fall, what is the worst that can happen? A bruise or cut that will heal completely within a week. When you are older, that slip on the border of balance can cost you a bruise that will last a year, if you are lucky enough to avoid a broken bone.
