“Think about what happens on Earth when you throw up. You throw up and ...” — Chris Hadfield Quote

Think about what happens on Earth when you throw up. You throw up and you have a bag of something horrible and then you throw it away, but if I have this bag, what am I going to do with it? This bag is going to stay with me in space for months, so we want a really good barf bag.

You should have a fear of some things. That doesn't mean it incapacitates you from your ability to figure out a way to deal with it.

When I did my spacewalks, it was during space station construction. So the shuttle was docked to the fledgling ISS at the time. So we would always stay tethered.

No aeroplane you've ever gotten into had less than thousands of flights before they took their first passenger. Because vehicles are unsafe at first.

Probably the biggest temptation that young writers face is to be entertaining, to show your bag of tricks and do a bit of tap dancing. I read a lot of things, and I keep seeing this brocade of voice where someone is trying to be too pally with you or ingratiating on the page.

After a workout, I have a protein drink and always keep a protein bar in my bag.

If I don't go to the gym and work out, I look like a bag of bones. I go three times a week usually and it's nearly all weights work to help with definition.
