I really don't want to predict the future, because if I know what will happen around the world tomorrow, nothing can be surprising anymore. I will definitely lose passion and interest for the rest of my life. This reminds me of a very interesting TV play that was aired many years ago. A group of people traveled back 2000 years in time. Occasionally, the main characters took the medicine which could help the emperor live forever. The emperor died, but they lived for 2000 years. When they finally got reunited with their family, they knew that everything was over. After that, they lost the power of predicting the future. They didn't know what would happen tomorrow which was very different from what they have experienced in the last 2000 years. In fact, everyone can predict the future. For example, when the sun rises and sets. Spring will definitely come after some days, etc...
