Can We Go Back?

I realized after reaching campus today that I forgot my cell phone. I thought about going back to get, but I stopped. Hadn't I lived life without a cell phone once? Is it possible to live today without one?

I decided to experiment. I won't carry my cell phone for the rest of the day (until midnight tonight). I want to see if I can handle not having it, or if carrying my phone has become an addiction. Already I feel an urge to be connected.

Oh, this is indeed a philosophical conundrum.
