Chris Hadfield on Going Blind in Space
What's the most dangerous thing you've ever done? In this TED Talk, Commander Chris Hadfield gives us twenty minutes on the most dangerous thing he did, which was strap himself into a NASA Space Shuttle, facing odds of catastrophic failure somewhere around 1 in 40. Oh, and he did it twice, not to mention his trip on a Soyuz. He made it, though at one point on a spacewalk he managed to go blind for a while (!).
Sample line: "In the astronaut business, we have a saying: There is no problem so bad that you can't make it worse." Enjoy. (Warning: there's a Bowie cover at the end.)
