Would you be happy if you could live forever?
This was  question of a university's question, and was dealt with in my work place. I had  to answer this question for my student. I thought a little moment, and then I answered following.
In my opinion, immortality is not always happy because if you became a fatal malady, you would have to suffer from the disease. Moreover,  if no one would not die, overpopulation would cause food shortage and could not keep space to live. But The earth do not have the room for those problems.
What do you think about this?
