The article is about US stock prices rising. Let's quantify the rise as 10%. Perhaps around 200 million people own, directly or indirectly, US stocks, and the stocks of each person are worth an average of maybe 1 year's income. Thus, the price increase for each stock owner is equivalent to about 10% of income for 1 year. If income is equivalent to, say, a third of the time spent earning that income, then the price increase is equivalent to about 3% of a life-year per person. For 200 million people, the total comes to 6 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 6 million / 40,000 = about 150 characters.
Comparing the space devoted to articles in Human News and on the front page of the standard newspaper, this article occupies 8% of Human News and 3% of the standard newspaper.
