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
=======
Alpha-blockers, also known as α-blockers or α-adrenoreceptor antagonists, are a class of  pharmacological agents that act as antagonists on α-adrenergic receptors (α-adrenoceptors).Historically, alpha-blockers were used as a tool for pharmacologic research to develop a greater understanding of the autonomic nervous system. Using alpha blockers, scientists began characterizing arterial blood pressure and central vasomotor control in the autonomic nervous system. Today, they can be used as clinical treatments for a limited number of diseases.Although alpha blockers can only treat a small range of diseases, some of them have clinical uses, such as having the ability to treat hypertension, Raynaud's disease, erectile dysfunction, etc. Generally speaking, all of these treatments function by binding an α-blocker to α receptors in the arteries and smooth muscle. Ultimately, this relaxes the smooth muscle or blood vessels, which increases fluid flow in these entities.
