Each Rhino has a sizable Corps of Impulses, each dictating the pace and imperatives of the area they supervise. No two rhythms are just the same, doubtless because the goals of each system are different. What your ear needs to function right is not the same as your knee or toenail. Each system has its own clock and each clock has a monitor. Impressive organization, huh? And no job interviews.
Nature is really on top of things.
