my life will disappear
but earth will continue to live.
but this earth will also disappear.
why do we need to think about todays problem.
what is the significance of thinking about society and the mystery of our world.
i am 21years old.
my life will be end at 80
so i only have 50years.
my life only last 50 years.
so sad to live, to think. i dont want to think about all of the problem
