If only I could send you "spare time," (or a round-trip ticket for a two month vacation in Thailand), instead of just sending further obscure ramblings on "spare change"
My guess is that you may have meant to qualify your statement so it read:
I need about 6 hrs spare time every thirty minutes.
But, another guess: you ran out of time to extend your response.
But, my psychic powers do grow dimmer, these days, in spite of brilliant sunshine, and daily temperatures in the mid-to-high eighties Fahrenheit, here.
"What do humans depend on: words ! We're suspended in language: we can never say what's up: or, down. We must communicate experience and ideas, but in ways that do not become ambiguous, and lose objectivity.
For parallels to quantum theory: we must turn to psychology, or to paradoxes thinkers like Buddha and Lao Tzu illuminated, examining reality, as both observer, and actor, in human life's small-scale micro-cosmic drama."
