When Sathapathi entered into his one hundredth year hale and healthy without any problems that the age old people do have and can do all his works actively, he felt worried rather than feeling happy why his nature was not like all the other old people. The other worry he has was he might remain alive like that and never will die. He started writing his life as a book from the birthday of his one hundredth year till the day of his death on one hundred one birthday and he titled the book as 'Shadows in the Twilight'.
