Thank you very much.
Dr. Marshall, I want to echo what has already been said. It has been one year, with volunteers, and the robustness of this report is excellent. Thank you very much.
I have also had the experience of having a father who served in the military during the Second World War. He came to live with us, when he was 71 years old, with a cane, with glasses, and hardly able to go up and down stairs. He has now moved out. He goes up and down stairs with vigour. He does not wear glasses—he got laser surgery for his eyes—he threw the cane down, and now he coordinates a walking program at a shopping mall, and frankly, he can probably outrun me.
