28-year-old Naren Tumung's memory loss is slowly improving. He can now recall the moments before the blast on October 30 2008 in Assam which killed close to one hundred people and injured several hundreds. He parked his auto rickshaw under the Ganeshguri flyover in Guwahati and went to a nearby tea shop. Just then the bomb went off. Naren wasn't injured and ran to his vehicle when a second blast blinded him. He can't recall what happened after that.
