We'd be doing the same thing we always did. The Internet is a very recent phenomenon.
I grew up in Oz where there was no TV till I was 19. I still love all the radio drama/comedy/quizzes and so on they used to broadcast. And, of course, there were no mobile phones till the 1990s.
These days we are all speaking a language that few of us would have understood even 20 years ago.
Well they would just go mad , as Internet has a big influence on all our lives!
I never had it growing up and didn't start using it until the the mid 90's maybe. The only thing that would really bother me would be that I would have to go shopping for things again. That and not having this website around and missing online PC games. We would just have to go back to the old ways of doing things. Good or bad ? Each has a point.
People would: Exercise more, talk face to face more often, hike, ride bikes, travel, play outside, sit on the patio, get more sunshine, get to know their neighbors, catch fireflies, have water pistol fights, plant gardens, volunteer, buy more magazines and news papers, learn to spell correctly, have smaller butts, just to name a few.
I grew up without it and had an awesome childhood.
We use the Internet to communicate more than ever and it’s become an integral part of any standard means of communication.
Have a normal life and go for a hunt? :)
