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
=======
A light and air unit, also known as a breathing support unit, is a specialized piece of firefighting apparatus used by firefighters to provide supplemental lighting and SCBA air bottles at the scene of an emergency. During prolonged emergencies, particularly structure fires, where firefighters must remain on air (wearing their SCBAs), these air bottles will need to be replaced and refilled. The light and air unit has the ability to refill the SCBA bottles while in the field using onboard air compressors. It also carries a supply of spare air cylinders. These units are highly customizable and can vary greatly between departments. These multifunctional units are also equipped with diesel generators which supplies electricity to power portable lights and overall scene illumination. This is usually done via a roof mounted telescoping light bank. The unit also has the ability to supply electrical power in an emergency to a shelter, base camp, or medical facility.
In the United States, Chapter 24 of National Fire Protection Association regulation 1901 outlines specifications for any air system mounted on firefighting apparatus.
