Not much more astonishing than Marie Fredriksson: she survived a brain tumor after being given only a 5% chance. As a result, she lost sight in one eye and had to relearn how to read, among other things. She's now in the middle of a world tour with Roxette that began in Feb. 2011 and won't finish until Sept. 2012. They released an album last year and another one this year, and she's continued to improve throughout. Amazing woman.
