When you walk by someone you don't know do you acknowledge them? I do and now I do it as an experiment to see people's reactions. On one of my 75 Hard outdoor workouts I said hello to a couple people and none of them said hi back, some not even looking at me. What am in invisible? Am I doing something wrong? Am I that scary? Maybe I'm just over thinking it...in this episode I explain an idea that may answer all of this.
