Anupam Kher visited late actor Satish Shah's residence and met his wife Madhu Shah, who's battling Alzheimer's disease. Anupam said Madhu's memory fades in phases and at times she forgets that Satish has passed away. "For a flicker of a second, she said, 'Chala gaya'...she had tears in her eyes, and then again she lost her memory," the actor said.
