Cosmos and Steroids - Psychology of Communication

Cosmos
For a long time, people had dreamed about going to cosmos. However, it takes long time to reach the moon and cosmos. By radio contact, people tried to sent messages to the cosmos, but it didn't come true. I think that in the future, scientists can discover how to reach the cosmos fast, so we can explore the space.

Steroids
Nowadays, we can easily see many athletes who take steroids to win the games. Although people's opinion about plastic surgery become more positive, they can't accept the steroids as positive things. But, people expect athletes to be more excellent than ordinary people in the performance-enhanced society. I think that taking steroids is not good, but it's difficult for athletes to avoid taking the steroids in this society.
