I'm curious what the long-term impact of covid is going to be. We're seeing more data come out, e.g., this study from yesterday where 11% of people who had "mild" covid had impaired lung function one year later, with no observable improvement in trajectory over time (measured as % of people impacted), which nicely complements studies that show long-term impact on the heart and the brain

The questions I'm most curious about are what the cumulative impact will be and what impact vaccination has.
