I admire people who do things I know I couldn't do and at the moment, people who climb the highest mountains in the world, a particular interest of mine. But at various points in time I admire some of the teachers who lead schools in very difficult environments. They have immense courage, they do a job that I know I couldn't do. So I tend to admire people who do things that I know I couldn't do and unfortunately I find there's a huge amount of them in the world.
