As the death toll for selfie-related incidents grows ever higher – including animal attacks and weapons misfiring – why are people risking their lives for likes?

The number of deaths in 2015 related to the practice of taking selfies has risen to 12 after a 66-year-old Japanese tourist, Hideto Ueda, died when collapsing and falling down stairs posing at the Taj Mahal in India. His travelling companion survived, but suffered a broken leg.
