People of the Himba tribe are not so easily fooled by optical illusions like this. The Himba can be found in the small town of Opuwo, Namibia in small numbers.

We live in an age where people pay a pretty penny to go under the knife and change their appearance. Tummy tucks, lip fillers, nose jobs, and breast implants are all now commonplace. According to neuroscientist, Moran Cerf, one day there will even be an operation to make you super intelligent.
What does it mean to be intelligent?
