The edge where everything important happens, because nothing interesting lives in the middle.
means The outer edge or border of something circular or hollow, like a cup, wheel, or basin.
from From Old English 'rima,' meaning border or edge, as in 'sǣrima' (seashore) — literally the 'sea-rim' where land meets water. It has Germanic cousins, like the Old Norse 'rimi' (a raised strip of land), and stayed close to home: the word for 'edge' has barely budged in a thousand years.
