What do American Presidents John Adams, Thomas Jefferson, Martin Van Buren, John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, and Calvin Coolidge all have in common with each other? Two things. These nine men served as Vice-Presidents before becoming Presidents; and they are no longer with US.
Additionally, they have something in common (or should have something in common) with all the citizens of the United States.
They were just ordinary people yearning to pursue a peaceful life, individual liberty and personal happiness. Why? Because living on this planet earth doesn't get any better than that!
