What's more precious than blood?

People run after things that other humans have created.Sometimes I feel like being an invesigator,someone who has filled a role and observing things happening.Its strange but it feels good cos' I have the impression that all these are just a resultant of one's senses.If we were blind,our ears and sense of touch would have been the only witness of this world.Death is just the absence of senses.Who hasn't watched a film where the hero is just a normal human being unaware of his powers until uncovered?
