Mumbai, Jan. 16 -- For 91-year-old Madhav Nene, a former government employee, running is a way to feel young. "It is necessary for one to be healthy and fit," says Nene, who, along with his 88-year-old brother Vasant Nene, will be taking part in Tata Mumbai Marathon for the second time. "I started running after turning 90," says Nene. This year, the whole Nene family will be joining the brothers for the run. While Madhav's nephew would be running 42km this year, his two female relatives will take part in the dream run. "I do nothing different, just walk normally. When they see me running, they appreciate it," says Madhav. yesha kotak...
