Clouds of gas and dust don't emit light, yet we know they exist and can estimate their mass. Couldn't we apply the same methods to Dyson spheres if this was the case?

From their conclusions, I wonder if there is some kind of "use-it-or-lose-it" effect going on in the sample of older physicians, which does not affect the sample of younger physicians as severely due to their age. That is, the high volume physicians are kept sharp by the high patient workload regardless of age.

Authors' conclusions reproduced below:

"Within the same hospital, patients treated by older physicians had higher mortality than patients cared for by younger physicians, except those physicians treating high volumes of patients."

This isn't the first time we've heard first-hand accounts of massive companies treating workers like slaves. Amazon is already notorious for the ways it treats its warehouse workers. Once again, upward concentration of wealth in our country has created pressure on the people at the bottom to produce more, more, more. If you don't see the parallels to the time period leading up to the massive workers' rights reforms of the Progressive era - you aren't looking very hard. We seem to have have already forgotten the lessons we learned just a century or so ago.
