If the internet was no longer it would greatly affect my life, it would take time to adjust. I use the internet to stay connected to family and friends. I use it to find side jobs, search for music, banking. It is something that I use everyday, but I don't let it affect how much time I spend outside, or getting involved in activities.
The hardest adjustment would be my banking. I would probably not pay all my bills on time without the convienience of pushing a button. I would find it a lot more difficult to find side jobs and jobs for that matter. Drop off a resume?
