Many years ago, there was an amazing TV show about time travel which was very popular in my country. The hero travelled 2000 years back in time to the Qin dynasty era 2000. In order to contact his family who lived in the 21st century, he carved a letter on a stone and buried it near the place where his house would be. Fortunately, his parents coincidentally dug (“to dig” is an irregular verb) it out and knew that their son was still alive in another space-time. In order to avoid to make a Butterfly effect which could change history, our hero found a drug that could keep him immortal until he saw his parents again. So, if time travel is possible, I still want to go to the place where I live now regardless of the era. If I am lucky enough, I can live long enough to reach our era again with a special drug. But I have seen another man in a movie who travelled back to the Jurassic Period, it's terrible!
