Why They Call it Lunacy

I've been thinking some on the way bodies and minds and ocean currents are influenced by the phase of the moon. From tides to menstrual cycles to cycles of psychotic breaks, much of the flow of this world in somehow connected with lunar patterns. Why is that? From almanac listings of best days to plant to days or nights when fish are biting, the craterous rock in orbit around us seems to have an awful lot of say in our affairs. How might things be different if we had two or three moons instead of just one solitary rock? Can a moon have moons of it's own? If that were the case with us, would earth be the "grandplanet" (like grandparent) to the moons of our moon? How would earth be different if our moon were bigger or smaller than it is? I see several ways our moon effects us. How does earth shape conditions on the rock? Are we in symbiosis? Or just happenstance?

Why do I care? (yep, you can tell when I hit day 3 or day 4 in my insomnia cycle...the old grey matter starts drifting any ole which way.)
