Curiosity is a question mark.
We are born curious creatures. We learn at a rate that a computer could not hope to quantify before we even understand what a computer is. Curiosity and reason are as inbuilt as love. I don't doubt that in years to come the curiosity gene will be discovered with a big "I told you so" written all over it. The truth is the gene is unimportant; exercising curiosity is what really matters.
Time seems to go so fast that we are being dragged along with it like barnacles holding fast to a speeding ship. The temptation for the human being in this state is to accept, anything. Be it the status quo, the safest option or whatever is handed to them on a plate. Sometimes all of the above.
Question everything. If you see an irrational world, question it, dig deeper than what you are told is the answer. If you yourself have an irrational thought, question yourself.
