I want to say something right here. You all might（可以〔用于礼貌地提出建议〕）, this might（可以〔用于礼貌地提出建议〕） make you all think. Life is not really long. Let's say the average（平均的） person 30 years old. If you're 30 years old, you would not be about 7 years old. How can I prove（证明） it?

  At about the 7, 8, 9 hours you slept for 30 years. Out of 30 years, out of all the nights, last night when you were in the bed and woke up this morning, you don't remember a thing. You've been unconscious（无意识的） for about 8 years. If you're 30 years old, you slept by 8 years. Okay（好）. How much traveling have you done in 30 years?

  From the television station to home, to another country, to another city, to school, to church（教堂）. You've probably traveled 2 years your life, but it's just getting back and forth（向前） to where you're going. So there's 8 years of sleeping, 2 years of traveling. There's 30 years out of your life before you accomplish（完成） anything.
