More and more women are becoming involved in extreme sports, accomplishing major feats, participating in dangerous expeditions and unorthodox adventures. Who are these intrepid women who are willing to face great physical dangers, push their own limits, or even risk their lives, for the sake of a cause, an ideal or simply a powerful desire? Why and how do these women succeed in returning safely from dangerous expeditions that most people would be unable to cope with? What in their past made them capable of taking such risks? Is there an explanation for their great self-confidence and for their trust in the world around them? Catherine Reverzy is a psychiatrist and psychoanalyst.
