• Gender Studies
An analysis conducted in 2000 by sociologists in New York found two distinct patterns in the timing of affairs. A married woman's likelihood of straying is highest in the first five years and falls off gradually with time, according to the survey of 3,432 U.S. adults. Men have two high-risk phases, one during the first five years of marriage and, the second, after the 20th year.
