Do Ergonomic Keyboards Prevent Wrist Pain?
Two reviews, one of which separates mouse use from keyboard use and finds only one of them associated with anything. That distinction was missing from the first version.

Does Having Your Phone on the Desk Hurt Your Focus?
One 2017 study launched a thousand desk-drawer policies. The replication record since then is worth knowing before you build a habit on it.

The claim that breakfast sharpens your focus rests on a research base that looks very different once you separate adults from children. Here is what the reviews actually found.

Why Are Video Calls So Tiring? What the EEG and Camera-Off Experiments Found
Video call fatigue has been tested with EEG in a lab and with a camera-on field experiment at work, and both found effects. The explanations for why remain untested hypotheses.
