The story (from Mashable) that more people have died this year from taking selfies than from shark attacks did the rounds this week. As my Grim Reaper says, this is technically correct but the people that died either fell down stairs or turned their back on wild animals while trying to take a selfie, so the act of selfie-taking is probably more correlation than causation.
The more notable part is people taking selfies seem to think this imbues them with some sort of immunity from danger, like nothing bad can happen to you while trying to take the perfect cheek-to-cheek Blue Steel.
Also, give sharks a break. You are much more likely to be killed by mosquitoes, hippos, cows, deer or jellyfish than a shark.
