This study shows that about half of people wearing headphones in public do it just to avoid having to talk to other people. I definitely can't take care of a workout without headphones but I'm also that guy for sure; I wear headphones to the mall to avoid conversations with anyone trying to sell me things I don't need. Remember when going to the mall used to be fun? An Event? All the mall does now is give me anxiety!
P.S. Same study says that 23% of people wear headphones as a fashion accessory! What?!
