wikipedia said:On August 30, 1918, Fanya Kaplan, a member of the Socialist Revolutionary Party, approached Lenin after he'd spoken at a meeting and was on his way to his car. She called out to Lenin, and when he turned to answer, fired three shots, two of which struck him in the shoulder and lung. Lenin was taken to his private apartment in the Kremlin, and refused to venture to a hospital, believing other assassins would be waiting there. Doctors were summoned, but decided that it was too dangerous to remove the bullets. Lenin eventually recovered, though his health declined from this point, and it is believed that the incident contributed to his later strokes.
What if Miss Kaplan had stayed at home, and Lenin survived the 1920s without suffering any strokes, eventually dying from natural causes in - say - 1942, at the age of 72?
