We've all been told at one point in life that a human learns something new every day. I've been wondering about that for a while. At some point don't you think that if a person walked through life, oblivious to everything around them they wouldn't be able to learn something new every day. Say If I walked around for a day, staying secluded from everyone. With my only company as my mind, and not really seeing or hearing what went on around me could I truly learn something new. After all I already know everything in my mind even if I don't always think of everything in my mind.

Just a thought
