Meenakshi Amma belies her 78 years with the prowess she exhibits at kalari, thought to be India's oldest martial art.
The great-grandmother in Kerala, southern India, has been a driving force in the revival of kalaripayattu, as the ancient practice is also known, and in encouraging girls to take it up.
"I started kalari when I was seven years old. I am 78 now. I am still practicing, learning and teaching," she told AFP.
Kalari, which contains elements of dance and yoga, can involve weapons, such as swords, shields and staffs.
