"Those who rent Port-a-Potties have a way to
collect the urine and sell it to pharmaceutical companies. Pharmaceutical
companies separate urea and use it in drugs, lotions, makeup, and other mixtures
we-the-general-public cluelessly buy."
You are absolutely correct. They only gather the urine from the urinals
in the porta-potties - they don't separate anything collected from the 'sit
downers.' This urine is then sold to pharmaceuticals and an extract is
made that becomes a prescription drug for clearing out the arteries. If I
remember right, that drug costs in the neighborhood of $250 a month.
The owner of the Porta-John company who was the first one to sell this urine
to pharmaceuticals, is interviewed in the video "Urine: Good Health."
