WHY: The word
That one word question that makes an individual think upon whether the facts which one has learnt are right or wrong.
That one word question that is sufficiently asked by people who turn out to be thinkers, philosophers, leaders, scientists and other wise men.
And most importantly, that one word question that one asking frequently to oneself leads one to live one's life as a good person.
Though at times asking this question might make you feel awkward, it is always ok to ask it for once, otherwise that word with respect to any topic will be a Question burning in the back of your brain for the rest of your life.
