"We usually say of ancient persons, that they have already one foot in the grave, and the rest of their life is nothing else but the bringing of these feet together"

This quote by John Pearson is a metaphor for the idea that life is limited and that death is inevitable. He is suggesting that when we reach a certain age, we are currently on the course to death and the rest of our life is merely a matter of time prior to we reach the end. This quote is a tip that life is short and that we ought to take advantage of it while we can. It is also a suggestion that death is a part of life which we ought to not hesitate of it. We need to accept it as a natural part of life and utilize it as an opportunity to assess our lives and make the most of the time we have actually left. Eventually, this quote is a tip to live life to the maximum and to value the time we have.
