The expression and pose is something to think about when taking selfies and the venue is another. While most do not think of the venue it can show some aspects of you if most are in a bar or with a drink it can show that you are more likely to be found. Still a photo will not tell all and selfies tell even less.
I do not understand the craze to take a picture "A selfie" at the risk of death. Has vanity overruled commonsense?
