The decline in coronary heart disease (CHD) resulted in about 900,000 fewer deaths in 2002 in the United States. Interpolating the number of deaths prevented in earlier years gives about 15 million. If the average remaining life expectancy of a CHD victim was 20 years, then 300 million life-years were saved.
Human News aims to devote 1 character to each 40,000 life-years, or 1000 average lives. Thus, this story has about (300 million) / 40,000 = 7500 characters. Since this story is shorter than that length, there is space left over for future, potential, related stories.
