last time, when i perfused a mouse, and took out its spinal cord and brain, I felt exact the way you expressed. I felt nothing on the live but concentrated on dissection. it is such a beautiful and "holy" thing. I think last time when I was in the "body's world", i stayed too long ( more than 2 hours), and only after that, I felt the immoral....and when I started to think how they perserved all the arteries only but got rid of all the flesh and borns, it seemed that the people were tortured.....Maybe after 2 hours, illusions came to my mind...
