What I mean is are you social and wave and strike up a conversation, etc. or do you focus on your activity be it jogging, walking, biking and ignore the world around you? Personally I try to ignore everyone because I am not out there to form a social club but to get some cardio in and it's time for just me. It doesn't hurt I have an MP3 player going but I don't keep it so loud I don't hear all outside noises as that could be dangerous.
What do you do?
