My mother objected to me spending too much time reading and not enough outside.
I imagine there were people in the stone age that objected to people wasting too much time near the fire and not enough fighting with sabertooth tigers.
Exactly that! When I was living on the street, we used to call the fire "stoneage-tv".
Because the human brains have such a long history of staring "into" the fire, I have the mild suspicion, that reading on e-ink displays without a backlight might make it less likely to get lost in thoughts, than when staring on a "glowing" screen.
Unfortunately the only competetive screens are still rather expensive (paperlike)..
..damn, I got lost in offtopic thoughts again! ; )
So at the end of the day we learned that nothing ever really changed.
