Tech Stress, from Nils Poertner
Tech Stress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics
Valuable book on how to use technology and tech devices in a healthy manner, eg, author talks about the importance of having desk screens high enough, so we don't point our head downward too much (which is unnatural). Most visual "issues" could perhaps be avoided with proper habits. (I suppose in a good high school, pupils ought to be made aware of those things but then the teachers themselves aren't educated here…)
