They do walk around like absolute zombies, from my perspective it is funny, fascinating and sad to see so many people with all the potential that being human is, acting so robotic. Are they zombies caused by the chemicals, and radiation in our new and foreign world? or are they just locked into their own lives by the tech that they use that they are incapable of even seeing other people around them.
Not long back, I took a train ride and saw beautiful countryside and some places I'd never seen, The guy opposite only saw the screen on his I-phone.
Good journey
