If I were to get a free ticket into outer space, I would not go. The reason why I wouldn't because there is a very slim chance I would actually survive, and I don't want to lower the chances of me surviving by leaving the earth's atmosphere. That is one thing I would be afraid of. If I were to go, the most exciting part would be the 0 gravity, I would do backflips in the air and try different things I couldn't do on earth. One thing I would change is the way you use the bathroom in space. I heard it is very disgusting and it is one of the absolute worst things being in space has to offer.
I got hit with a baseball right in the back of the skull, I saw two of everything for a week and I still had to carry a block of ice home every afternoon.
