Ok..I understand the math example. Not sure the author should be paid a % of the printing and distribution costs for hard copy.
I did read your Old Hippie post and have been a Hippie wannabe forever. I just love the Ideal, but realize it will never be possible this side of Eden. And, Junior, I will be 63 next month.
I was a hippie, and trust me, it was over rated
(except for the free sex part). Dirty, unkempt, drugged out people are not fun to be around. Never got into drugs, was not all that interested in body painting or putting big daisies on my car. Intellectually, it was even worse.
As someone once said,
My hippy happiness got jaded by all of the scars.
