How well do we know our parents? Where we came from? How well do we understand the circumstances and situations that swirled around them at the time of our conception? And not just our individual conception, but the conception of our siblings, the creation of our families?
Where will you be when you are old? With your family? Your fiends? Alone? Will you be rich? Or poor? In good health? Or ill perhaps? Will you be mentally engaged? Or failing up there in some frightening way? How, and with whom, will you while away the hours of the day?
