People who responded to the survey have sex about 100 times per year. If the survey is representative of the adult population of about 4 billion people, then people have sex about 400 billion times per year. If we assign an arbitrary value of, say, 0.1 life-day per time, then the total equivalent value of sex is (40 billion life-days) / (365 days/year) = 100 million life-years per year. If we limit the scope of the story to one year, then the total value is about 100 million life-years.

Human News aims to devote 1 character to each 40,000 life-years, or 1000 average lives. Thus, this story can have about (100 million) / 40,000 = 2500 characters. Since this story is shorter than that limit, there is room for related stories in the future.
