Just been to see the movie Gravity. What a roller-coaster of a ride! It had me totally believing in the situation, despite the fact that some astronauts say there are obvious errors. For instance, Sandra Bullock's hair should have been flying upwards when she was weightless. Best of all, I liked the comment of a female astronaut, Catherine Coleman: 'There's no way - ever - that any female astronaut would ever let go of George Clooney. Under any circumstances.'
Can you do sex in space? Not sure, but I guess the scientists are working on it!
