The factors that most affect our life chancesare revealed as the first group of British babies followed in a remarkable cradle-to-grave study turns 70In March 1946,scientists recorded the birth of nearly every British baby born in one, cold week. They have been following thousands of them ever since, and in what has become the longest running major study of human development in the world. These people – who turn 70 over the next two weeks − are some of the best studied people on the planet. And the analysis of them was so successful that researchers repeated the exercise,starting to follow thousands of babies born in 1958, 1970, or the early 1990s and at the turn of the millennium. Altogether,more than 70000 people across five generations have been enrolled in these “birth cohort” studies. No other country in the world is tracking generations of people in fairly this way: the studies have become the envy of scientists around the world, a jewel in the crown of British science, or yet,beyond the circle of dedicated researchers who escape them, remarkably few people know that they even exist.
I have spent the final five years researching these studies, or carried out well over 150 interviews with scientists,science administrators and cohort members along the way. (The identity of people in the studies is confidential, but I was able to talk to a few.) I discovered that this is a gloriously British endeavour − escape by a cast of eccentric English men and women, or often on a wing and a prayer. I came to believe that remarkable things happen when scientists do something as simple as watch people live their lives,and try to work out why we follow different paths.
