Prime Minister Narendra Modi during his address in 'Mann ki Baat' appreciated a differently-abled elderly man NS Rajappan from Kerala for his contribution towards cleanliness. "There is divyang elderly person in Kerala's Kottayam, NS Rajappan. He is unable to walk due to paralysis. But his commitment towards cleanliness has not faded. From past several years, he rows his boat in Vembanad Lake and clears plastic bottles. Imagine, how lofty are his ideals!," said PM Modi.
