Island of horrors … or rhythmic gymnastics Olympic site?

Rowing through Sewage Bay in the 2016 Summer Olympics seems like a pretty good deal compared to visiting Brazil’s Queimada Grande island, which is the only place on earth the Golden lancehead viper can be found in the wild.

As poisonous snakes go, it’s probably pretty high up there on the list of ones you don’t want to tangle with, though nobody knows for sure because there has never been a documented case of a human being bitten by one. Still, evidence suggests you’d do a blood-gushing-from-everywhere Ebola imitation so cue the irrational fear!
