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
=======
Bitolterol mesylate (Tornalate) is a short-acting β2 adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and COPD. In these disorders there is a  narrowing of the airways (bronchi and their ramifications) that carry air to the lungs. Muscle spasm and inflammation within the bronchi get worse this narrowing. Bitolterol relaxes the smooth muscles  present continuously around the bronchi and bronchioles facilitating the flow of air through them.

Bitolterol is a prodrug of colterol. It has a rapid onset of action (2–5 minutes) and may last up to 6–8 hours.
The drug, alone or in co-administration with theophylline, doesn't show cardiotoxic effect.The U.S. Food and Drug Administration (FDA) approved bitolterol in December 1984. The drug was withdrawn from the market by Élan Pharmaceuticals in 2001.
