Timeline doesn't matter too much, but it's about 400 years in the future.
1) If someone sliced open a person's shoulder with a knife (combat knife, not serrated) and managed to slice through the major vein there, how quickly would they go into shock from blood loss, and then lose consciousness/die from it?
2) If the planet has a blue sun, what color would the plants be? A bluish tint, or more red, since there'd be more blue light to absorb? Also, it has a high "greenhouse" effect, so the UV gets through a lot versus actual light, so would that make a difference.
3) If someone lived in a space station all their life (around 22 years), how bad would his agoraphobia be, and how long would it last after he lived on a planet?
