Selfies are a pretty good litmus test for weeding out the weaker and dumber people among our ranks. 

At this point, taking a selfie is a pretty normal part of life. It was once seen as vain, but you'd be hard-pressed to find two people who don't take selfies of themselves on near near-daily basis. That said, not all of us are taking selfies in such dangerous situations as these brave souls. 

They aren't just vain, they're stupid too.
