the deer in headlights, the blink of an eye are interesting representations. You can make that argument of what is deemed unnatural on a lot since industrialization took root (and you did, as in cars). That genie is out of the bottle with world populations raising in lock-step to technology. Humans continue to live - in mega cities, with mass transportation, mass communication, world wars for more than 100 years. I don't know to what degree we biologically adapt, but most certainly we do adapt. Smartphones are yet another shock to populations that I'm sure we'll absorb. The web-accessed FT article on youth mental health, this conversation, this message board of worldwide concurrency are all adaptions.
