If I can...

If I can live for a long time, I might be lonely. My friend said that I can live a long and healthy life, because I am laughing all the time. I thought it again and again, and I thought that I would not like live for a long time. Because my family, my friend, and the people that I know will not in this world, and my life will boring. Maybe I can watch the world's changing, and I can know people in different generations. But the most important thing is that I will older than before, I may not have energy to do the thing that I want to do. I may just sit on the chair and can not go anywhere. I don't like it, so in my opinion I don't like live too long in this world.
