Can we live without the Internet for a day, a week, a month?

Here's a thought. If the whole world's internet structure was shut off for a week, what would be the impact? A total chaos of course in most cases; think aviation: e-tickets, self check-in; think commerce: amazon, ebay, e-trading, salesforce; think healthcare: teleradiology, online patient records, etc.

But I wonder what would be the human impact. How would we emotionally react to being offline? Would we throw our hands up in the air, go out in the park for a picnic, spend more time with our families, read a book? Or would we stress every minute of the week trying to connect ourselves back in any way possible to the world wide web.

It's an addiction. Isn't it?
