Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
The ancient Indus Valley Civilization of South Asia, including current day Pakistan and Northwest India, was prominent in hydraulic engineering, and had many water supply and sanitation devices that were the first of their kind.
Among other things, they contain the world's earliest known system of flush toilets. 
With a number of courtyard houses having both a washing platform and a dedicated toilet / waste disposal hole. The toilet holes would be flushed by emptying jar of water, drawn from the house's central well, through a clay brick pipe and into a shared brick drain, that would feed into an adjacent soakpit (cesspit). The soakpits would be periodically emptied of their solid matter, possibly to be used as fertilizer. Most houses also had private wells. City walls functioned as a barrier against floods.
The urban areas of the Indus Valley provided public and private baths, sewage was disposed through underground drains built with precisely laid bricks, and a sophisticated  water management system with numerous reservoirs was established. In the drainage systems, drains from houses were connected to wider public drains.
