I can
i have survived a whole weekend before. I remember i was so fed up with people, i went on a camping trip by myself to relax. I took my cell phone with me just in case something happened, but i kept it turned off. Only called my parents twice a day to tell them i'm fine. I took a hunting rifle and a fishing rod and i just had fun. I camped by the river, it was cool.
Back on topic, i can survive a day without my computer.
