Your eyes might have seen it all, from the seven wonders of the world, or even the illuminating lights of our universe.Your ears may have heard it all, a vuvuzlea swarm, an outdoor symphony, or perhaps an intriguing conversation on the train through your silent earphones.
Your nose might have smelt it all, (any) toilet in the city on new year's eve, or (much) better yet, the smell of a girl you like.
You may have tasted it all, among them, a noodle classic at 2am.
You could have felt it all, the foundations of the tallest building in the world, or if you're unlucky, the pain of a broken heart.
And after all that, after everything, you still might not have any logic, nor rationality; no common sense. Some people say "I think, therefore I am". Others say "ignorance is bliss".
