Blink and the whole world twists upside-down. Blink - someone dies and half of you is gone. Blink - you are gradually lost, and awaken one day without an anchoring equilibrium. Blink, you meet a stranger. Blink - you decide. Blink - your life is no longer what it was.
How many thousand times will you blink today? How many million blinks in a lifetime? A life can change irrecovably in the span of a single blink.
Case in point: six years ago, my world span inside-out due to a single careless wink. Blink and it could all be gone.
