In this inspired TED talk, Chris Hadfield, the first Canadian to ever walk in space and the first Canadian to ever command the International Space Station, talks about fear versus danger and what he learned from going blind in space.

There’s an astronaut saying: In space, “there is no problem so bad that you can’t make it worse.” So how do you deal with the complexity, the sheer pressure, of dealing with dangerous and scary situations? Watch and listen, as Hadfield paints a vivid portrait of how to be prepared for the worst in space (and life)—and it starts with walking into a spider’s web.
