Cold Sore Triggers. While symptoms are not usually present with an initial infection, certain factors may trigger later outbreaks of a cold sore. These can include exposure to sunlight or other UV light, the common cold or flu, hormonal changes, and emotional stress.
It was said that Marilyn was an occasional smoker. Although, looking at some of these rare photos it appears the habit was more than occasional. The first time Marilyn was seen sporting a cigarette on screen was in Right Cross (1950), though in her very first screen test she lit and put out a cigarette. She appeared on at least one magazine cover smoking a cigarette, and she is smoking in bed in the opening scene of Niagara (1953).
Representative of the more sensational (but still well-received) accounts of Monroe's life is Anthony Summers, Goddess: The Secret Lives of Marilyn Monroe (1985; 1986). A thoughtful analysis of Monroe's life, films, and changing cultural meaning can be found in Graham McCann, Marilyn Monroe (1987). Norman Mailer, Marilyn (1973), and Gloria Steinem, Marilyn (1986), perhaps illuminate as much about their authors as they do about Monroe.
