The article discusses tracking a group of people over time who are of the same age and how their health diverges.

To understand the relationship between politics and health in recent decades, we draw on individual-level medical data and death records from the National Longitudinal Study of Adolescent to Adult Health (referred to as the Add Health survey), which has tracked a nationally representative cohort of people who were adolescents in the 1990s (most born between 1976 and 1982) over the course of their lifetimes16. Unusually among health studies, Add Health includes a measure of political beliefs: self-reported liberal–conservative placement. It thus captures individual political orientation and medically validated health measures (for example, haemoglobin A1c (HbA1c) levels) and their changes over time, and individual-level cause-of-death data that extend into the COVID-19 era.

Something like Ansible won’t help you the first time around, but it’ll make the next times easier.

I think people should be able to call a wrong out without having to call all wrongs out.
