Are you in the habit of regularly posting selfies of yourself at the gym, or of things around you while you work out?
Well a new study that's out suggests that people who post work out pics of themselves are narcissists. The people on Facebook who like the pictures are really liking them just to be polite, but in reality, do not like the egotistical displays.
I can sort of see a point on this, although I have to admit, I'm a little guilty of this myself. Do you have a habit of taking selfies while you workout?
