For example, John Kennedy was elected president in 1960 while Abraham Lincoln in 1860, between which was a hundred years. Both men were killed from behind, on black Friday , and with their wives on the spot. The two men were born exactly one hundred years away, as were their murderers, Lee Oawald and John Booth. Perhaps the strangest coincidence is that President Kennedy’s secretary , whose name was Lincoln, advised the president not to go to Dallas, where the president was shot. President Lincoln’s secretary, named Kennedy, advised the president not to go to the Ford Theatre, where the president met his death.
