 I must confess that I had prepared a different concluding remark, but this afternoon, when excellent presenters made the invisible visible, it's impossible for me to finish with what I intended. I think this conference should all become advocates of the invisible. Therefore, allow me a very, very personal remark why I'm doing this. I could sit, I ask myself why I'm not sitting at the Reform Club in London or in a wonderful coffee shop in Ex-En Provence, enjoying my pension and reading in the newspaper about this conference. The answer is a different one. I think we are, we have to. We have to work to make this world a better place. I think we are all, as human beings, it is our fate to do everything that this world will become a better world, knowing that this will never be the case. Thank you all of you for being here. Thank you, Marian Young, Neil Stevens and Mifanue Taylor for working with us. Thank you, Comuniki, and thank all of you for being such a wonderful audience. Thank you very much. Thank you. Thank you.
