Chris Hadfield said everyone gets nauseous in space, but the will the get out there is greater. Also, the barfbags are supposedly astronauts bestfriend.

He also said the Space Station can be very smelly- the toilet is in the middle of the ship, there are up to seven people using it on a small ship.

But he added that ISS was not smelly- the ventilation system was good enough to clear the air.

Mir Space Station on the other hand ventilation system was not so good- "it smells like an old basement".

People train in water to prepare for space, but that's not entirely accurate- in space it's easy to start moving but it's harder to stop and swimming can't simulate that.

The new, inexperienced astronauts are a source of laughs for their colleagues cause they always bump into things.

If someone makes a mistake others will remember and make fun of it for a very long time...

... and the most popular is cracking the helmet during training in water. The cracked helmet is presented during the nearest morning briefing.

The astronauts listen to music chosen by their families, it is used for example for waking them up. Robert Curbeam's daughter chose Queen, while Scott Parazynski's son dedicated him the Star Wars theme.

By the way Parazynski got the nickname „Doogie Howser” cause he "looked twelve and just finished medicine", he hated it. Practically every astronaut gets a nickname and Robert Curbeam was more lucky being called „Beamer”.

Things that look nice from Earth are scary here, shooting stars are rocks traveling so fast they can rip through the Station.

Yi So-yeon from South Korea said they have relay races in ISS, but they look silly as you float around.

Jerry Linenger said he loves to sneak up on people and it's really easy on a Space Station.

After short flights in space the body needs time to adjust to gravity...

... while after long flights gravity makes you wanna fall and throw up.

You can "grow" in space. Yi So-yeon said she got higher in space, it took her 3 hours and it took her also 3 hours on Earth to get to her normal height but the pain was terrible.

Hadfield said it's hard to get used to masses of people around you on Earth, while Yi So-yeon adds being the first astronaut in her country made her a celebrity and everyone knows her now.

Watching Earth from a new perspective changes some views. Linenger said he was astounded by trees when he came back from space, he said the color green was so beautiful on our planet.
