Ahem, ahem. Pardon me for starting the challenge with the scariest topic of today's time - ageing and diseases. But it's high time we speak about it to learn about a condition that is fast growing today. Not many years ago, as I watched my grandfather helplessly succumb to the nameless monster we never knew existed, I wished we had a solution to his problem. But sadly, they said his condition didn't have much scope for cure.
