i just want to know your idea if what would happen to the world if everybody's happy... :-/ For me, everybody would avoid fighting, won't do any bad things... but maybe we won't be able to encounter any problems... unlike today, we saw some people who do crimens, and they forgot already about God... oh! what a mistake!! I hope we would be able to reach the happiness in the world... hehehe... :-D
