Dear Thyagarajan Sir, This kind of posts encourages someone to go all out to find the result. That is why I enjoyed every bit of the image puzzles in "Let us fire up the Neurons". For someone of my age, it eliminates Dementia and keep the mind active. Persistence is definitely the key. But Deepthy and Rihana made my job easier by guiding me in the right direction. They gave the gift of direction for someone who has lost his vision.
