Nimoy has said that the character of Spock, which he played twelve to fourteen hours a day, five days a week, influenced his personality in his private life. Each weekend during the original run of the series, he would be in character throughout Saturday and into Sunday, behaving more like Spock than himself—more logical, more rational, more thoughtful, less emotional and finding a calm in every situation. It was only on Sunday in the early afternoon that Spock's influence on his behavior would fade off and he would feel more himself again—only to start the cycle over again on Monday morning. Years after the show he observed Vulcan speech patterns, social attitudes, patterns of logic, and emotional suppression in his own behavior.
