[Sacajaweau]

Necessity is the mother of invention.

The world could start a million times and we would would repeat the same trail a million times.

I have always believed that the human brain is pre-programed and "living" taps this brain resource as needed...a process I call "pondering"...or the search for a solution.

And it probably has, if not a million times, then a whole bunch of times.
