How do they know to choose this plant? Think of it as "the other butterfly effect" — which could teach us to find new medicines for the treatment of human disease.

Khadija Gbla: My mother’s strange definition of empowerment

1,121,954 views


Khadija Gbla grew up caught between two definitions of what it means to be an “empowered woman.” While her Sierra Leonean mother thought that circumsizing her — and thus stifling her sexual urges — was the ultimate form of empowerment, her culture as a teenager in Australia told her that she deserved pleasure and that what happened to her was called “female genital mutilation.” In a candid and funny talk, she shares what it was like to make her way in a “clitoris-centric society,” and how she works to make sure other women don’t have to figure this out.
