For me, these are some of the most extreme human performers. Professor Damian Bailey might be one of the world's most extreme scientists. They seem to be better able to defend brain blood flow and extract oxygen so that mental agility seems to function better. In May, while conducting a study on the effects of extreme altitude, he helped save a man's life on Mt Everest. These very applied studies have allowed us to look inside the human brain and figure out how it works, sometimes for better sometimes for worse.
