In “The Life Project,” Helen Pearson, a features editor for Nature, chronicles the research for the 1946 cohort and the four other mammoth studies that followed. The original number, roughly 17,000, was soon culled down to a more manageable level, and death and attrition reduced it further over time. The septuagenarians were the surviving members of one of the first and longest “cohort studies.” Seven decades before, British researchers had begun the process of tracking-through childhood, adolescence and adulthood-every single baby born in England, Scotland and Wales in a single week in March 1946. Roughly 3,000 British men and women, all of them turning 70, all of them strangers to one another, celebrated their special day at two enormous parties in London and Manchester. This spring, a group of British scientists threw what was surely the world’s weirdest birthday bash. But parents with high hopes for their kids offer the ‘strongest buffer against disadvantage.’
