The veteran of four space flights and the American record holder for consecutive days
spent in space, astronaut Scott Kelly has experienced things very few have:
- What does it feel like to be launched in a rocket?
- What happens to your body in zero gravity?
- What do you do when you get a toothache 250 miles above the Earth?
Interesting story on Kelly and gene changes after he return. I do wish the story with go into detail on what were those changes? If he was to have children, will they have he "new" genes or the old ones?
