100 000 seconds is about 27.78 hours. When one of my classmates heard it, he was very amazing about it and said that he thought it would be a just little more than 10 hours.
Then, I told him, that we only have about 2.5 billion seconds in one human's life.
How long is one second? And how much is 2.5 billion?
Time is like the sand. One can't stop it flowing by his hand. Even
Einstein can not.
