Every year, since 2010, on the eve of Nelson Mandela’s birthday on July 18, the United Nations’ Department of Public Information celebrates 67 years Mandela gave to social service by fighting racism and empowering the underprivileged under it’s programme, United Nations’ Academic Impact.

The UN seeks to encourage youth around the world to dedicate 67 minutes of their life to social service. Last month, four Mumbai-based 20-somethings took the message very seriously. Trishya Screwvala, Samyak Chakrabarthy, Yaazdan Katrak and Ruchi Nirmal set up Raindancer, an NGO, to sponsor the education of primary students at Shree Ganesh Vidya Mandir at Dharavi, Sion.
