When it comes to taking up challenges, no one can match a sportsperson’s spirit. The #IceBucketChallenge, which is making waves on social media with the likes of Bill Gates, Lady Gaga and Hollywood actors uploading videos of ice-cold water being poured on their heads in order to raise awareness about Amyotrophic Lateral Sclerosis (ALS), has found celeb supporters in India, too.Tennis ace Rohan Bopanna took up the challenge, posted the video as the movement requires, and nominated others including actor Rahul Bose. However, Bose didn’t stand up to it and instead tweeted, "Hv decided not to waste clean water, but will donate!" But then, our other tennis star, Sania Mirza, took up the deed, not once but twice. She posted a video of "Take 2", because,"Some people thought there wasn’t enough water".
