Could it be aspect of religion that keeps us going? I mean, you can argue that there are a lot of Atheist that lived on without religion , but the religion i'm talking about here is not just god and devils, it's more like the ultimate concern of your life. If you are an athiest and depend on yourself, the society will be your god, they will be the one giving the chances. If you think that only money and touchable objects are the only things that exist, then materialism would be your god. For me, i think, these are what keeping us living.

Take Japan for instance, after a series of tragedy to them, quite frankly, there are no point living anymore. So many things are lost, so many hardwork lost. But one was not lost, their religion.

And these are just what i think, it is not aimed to anyone or a group of people with common interest in general. It is just an opinion. I know it gets a little sensitive when it comes to religions and stuffs.
