You need extraordinary mental strength and courage if you think of doing something which no one has attempted ever. This is what defines Poorna Malavath when she started her journey in Mountaineering. The film Poorna: Courage Has No Limit is a biopic made on Poorna Malavath, the youngest girl to climb the tallest mountain of the world: Everest. Poorna is now 16 years old but back then she was just 13 years and 11 months old when she scaled this mighty peak.
