"We know how we were born, but know not how we will die"

The quote indicates that while we understand how we entered this world, we can not forecast or manage how we will exit it. Death is an inescapable element of life, and as much as we may try to prevent it, we can not escape it. The quote might likewise suggest that we ought to live our lives to the fullest and not stress too much about our ultimate demise, however rather concentrate on the present moment and take advantage of the time we have.
