There are strange similarities in the life of John F. Kennedy and the life Abraham Lincoln. For example, Kennedy became a president in 1960, while Lincoln elected in 1860.This was exactly one hundred years apart. Then both men were shot after, on a Friday and in the presence of their wife. There is another very strangely similarity. Kennedy's secretary, named Lincoln, told him to go to Dallas. Lincoln's secretary, named Kennedy, told him not to go to the Ford Theatre. But all of them went and both were shot to die.
