I left my phone at home this morning heading out to breakfast. So I was without it for most of the morning. We survived as a civilization for thousands of years without them so it should not be a big deal. One thing this does is forces you to interact with others, to pay attention to what you are doing and frees you for things like real life conversation. There is a feeling of vulnerability without it because if an emergency were to take place it would be difficult to get help or to notify ones family/friends. Sometimes forgetting a phone is a good thing while other times you don’t know what to do with your hands.
