Chris Hadfield on Going Blind... in Space.

Astronaut and all around fantastic guy Chris Hadfield recently did a TED talk on how he went blind in space, and how to conquer your fears.

So today I learned they train them for pretty much every type of calamity that could happen, and then retrain them, and then train them again. They do things over and over and over again until they have it down to a science, so that when something happens, they are prepared for it.

It's an interesting talk, worth taking the 18 or so minutes to watch. He even picks up his guitar in the end and sings a little of his version of David Bowie's 'Space Oddity'...
