I'm not saying don't take selfies. I'm saying don't be an idiot and get yourself killed taking one, because it happens, and it really, really shouldn't.
For those who are unaware, here are some places that have come out in the news where people have been killed taking selfies. Avoid them, ok? Getting that angle just isn't worth it.
This story is what prompted me to write this card: a man who was taking a selfie near an Amtrak train in Seattle while standing in between the northbound and southbound tracks was killed when a train from the other direction came. He was trying to take a picture with the train coming on the first set of tracks when the other arrived.
According to reports from that railroad ALONE, 30 to 40 people are fatally injured by passing trains because they are on the tracks or near the tracks, and the conductors are not able to stop and an accident occurs.
So stay off the tracks. If you want a picture with a train, keep a SAFE distance! Think of them like high power cables-- you don't want to get close.
In front of dangerous wildlife
This isn't the only report, but there have been people mauled by bears after trying to take a selfie with them when they come across them in the wild, like the incident @yakwithalanwrote about here.
You never know what an animal is going to do when you approach it in the wild. You can't account for their actions. If you see a bear or other wildlife, follow the proper procedure to get away with it---the story is enough!!! You don't need a selfie to prove anything, and risking it could cause you serious injury. Or death. So there's that. Stay away!
I don't have statistics on this one, but there are multiple stories (here and here, for starters) about people getting into accidents while on their phone, or taking photos, or, in the case of selfies, doing both.
Driving is already dangerous enough as it is; don't take your hands off the wheel to get that driving selfie. If you want to make the illusion, just pull over and take it. Everyone will be a lot safer then, as you're also endangering others when you selfie + drive!
