The big thing to keep in mind with RSA in the real world is that all of the Numbers involved have to be big to make things really hard to break using the best algorithms that we have.

India's big population makes its GDP look big, but also means it has the largest number of poor people, infant deaths, maternal deaths in childbirth, and highest child malnutrition in the world.

International results are very important to me and it's vital that Russia go to big tournaments - we missed out on the World Cup but have made a big step now.
