I just watched BBC Knowledge; it was talking about how our body ages. But, what surprised me was that the scientists are trying to manipulate our genes so that we can postpone our aging. Well, it didn't really surprise me that much since we will still decay eventhough our genes are mutated. What shocked me more was a scientist made a theory that we can reverse the aging gene and make our decayed body grow young again. And it will make us immortal of aging. How long? 100 years? 1000 years? No. Even a couple thousand of years.

There is something interesting at the end of the show. The host, holding a yellow potion in a bottle, calling it the anti-aging potion, asked random people one question: do you want to drink this?

Some people said: yes, it would be interesting!
Others said: it might be interesting. but, no. I'm sick of this life.
When he came to young people, they say an absolute no.

But, there was one person said an intriguing answer:

no, I won't. What makes this life incredible is that we will die. If we are immortal, this life will be meaningless.
