11 of the most dangerous and incredible selfies ever taken

June 21 marks "National Selfie Day," but the ubiquitous photo style isn't as harmless as it may seem.

Incredible and sometimes dangerous events can unfold during the moment of inattention when people turn a camera on themselves. There are also photographers who seek out extreme danger as a backdrop for their selfies.

Getting the perfect snapshot isn't worth what some amateur photographers have risked — deliberately or otherwise. Several reports of deaths or serious injuries caused by selfie-taking have sprung up in recent years.

Scroll down to see rare selfies from around the world that capture some heart-pounding close calls and extreme dangers.

Warning: Do not attempt any of these shots.

Jared Michael was taking a selfie along a railway when a train zoomed past him at full speed — and just inches away. The train's conductor kicked Michael in the head mid-selfie, presumably to get him out of harm's way.

Michael walked away uninjured, and his original April 2014 YouTube video of the incident went viral. (It had 38 million views when we published this article.) He recently posted an explainer video, in which he calls himself a "dummy" and the selfie attempt a "stupid mistake." 

Reporter Kelly Nash was in Fenway Park watching batting practice when she decided to capture the moment in a selfie. A ball flew past her head right as the camera recorded a photo.

Nash didn't realize a baseball had nearly slammed into her head until later on. She told Fox Sports Florida "when I went to text [my family] the picture I noticed the baseball by my head!"

A thrill-seeker known as "Mustang Wanted" regularly posts photos and videos from atop buildings he climbs with no safety gear. The below selfie was taken in Dubai.

Mustang Wanted is an expert balancer, but his photos show an insane level of risk not worth attempting.
