I don't understand how large observational cohorts get published without either attempting to control for social factors or at least addressing why that might not be necessary
In other words, I'm not convinced that working too many hours will give you a stroke, outside of the societal pressures that force people to work 50+ hour weeks in the first place

agree. Tables say that both long working hours per week and years of exposure have nonlinear effect on stroke. This hints that there is further confounding at play.
