Remember Marina Abramovic and her Spirit cooking she was asked about recently?
watch?v=pScBQy5fk6o
Here she says she used "pig blood" because it was similar to human blood.
What wasnt widely known in the 90s until in 1993 they gave the nobel chemistry price to mr kary mullis is that since 1983 you can do dna tests even decades later on smallest pieces of human tissue by the concept of polymerase-chainreaction.
So I strongly suggest DNA testing on Marinas "beautiful poetry" to test if infact pig blood was used or human blood.
Also I strongly suggest a roentgen scan of mr tony podestas golden "art work" of a body in pain. looks like a headless body tipped in molten gold to me.
