I was out camping in the early nineties, and I had one of those Casio portables (TV) and I was listening to some "experiments" on human subjects using electric shocks to test a human tolerance level. I was hearing the tester speaking to the "victim" about the voltage levels at every succession to a greater voltage.
At some point the victim begged them to stop. They went further until the volunteer said NOTHING, meaning that he was beyond the threshold of pain and obviously passed out.
I was so angry I punched a tree and caused bleeding. I did not like the experiment using shock testing on a human. How much more so the testing of humble animals!!!!
Mind and matter are eternally the same
