So the area of the world is today the border between India and Pakistan. You should know from the map that India is kind of the belly of the east. If you go to the northeast, you're going to run into China. And if you go to the west of India through Pakistan, you're in Iran, the gateway to the Middle East. But this area of the world is very special if you want to grow food. You have a very fertile plain that runs around these tributaries and these rivers. And you also have very predictable weather.
