Cord cell transplants have cured 3500 babies in America over a period of several years. As cord cell banking grows more popular, and as research reveals new applications, perhaps 20 times that number will be cured in the next decade or two. The world population is about 20 times the American population, thus cord cell transplants have the potential to cure 3500 x 20 x 20 = 1,400,000 babies over a similar period. With an average life expectancy of about 60 years, that's about 80 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 80 million / 40,000 = 2000 characters.
