Thoughts on this series of works emerged during the reflections on transhumanism and humanity. We trade the lives of experimental animals in an attempt to extend human life. In this day and age of animal welfare movements, I hear very few voices about experimental animals. And I don't even know if it's necessary. When I got to the laboratory where they study genetically modified mice and other animals, I was extremely interested, as if I had entered a new world, but at the same time, the suffering of animals in this place remained in my head years later.
