About the cover
In 1946, a study began of all the babies born in one March week in England, Wales and Scotland, with a view to learning more about the social and economic costs of childbearing. Today the study is still going, and is one of the longest-running studies of human development in the world. The 1946 cohort has been followed into adulthood, so has allowed researchers to investigate how childhood health and lifetime social circumstances affect adult health and wealth. This week, the participants celebrate their 65th birthdays, the age at which many people in the United Kingdom retire. So now the National Survey of Health and Development has become a study of ageing. Helen Pearson talked to the surveyï¿½s scientists and members of the 1946 cohort about the scientific immortality that their participation has given them, and looks at how priceless the accumulated data have become.
