Fresh air is good if you do not take too much of it; most of the achievements and pleasures of life are in bad air.

Back in the day, we ate fresh; our parents cooked. Now, we're starting to think things are fresh because they're in a can, they're in a box, or they're frozen. That's not fresh. It's difficult to get real fresh.

You have to disengage at some point in order to be fresh.

It's important to bring things back from the Space Station because, unlike somebody living at the house where the garbage truck comes by twice a week, they don't have that in space.

Most time capsules, when they're unearthed, are really awful. There's nothing good in them.

The food isn't too bad. It's very different from the food that the astronauts ate in the very early days of the space program.

'Fresh Air' I listen to, like, every day.

I never worried about getting stale because the news and the people induce freshness every working hour.

Something people don't recognize is that being on the space station is probably a lot like being in some kind of confinement - like isolation.

As far as the sounds on the space station, it's pumps, fans, motors, certain modules are louder than others, but it's generally a pretty nice working environment. It's not too loud or too smelly.
