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 petechia is a small (1–2 mm) red or purple spot on the skin, caused by a minor bleed from broken capillary blood vessels.Petechia refers to one of the three descriptive types of bleeding into the skin differentiated by size, the other two being purpura and ecchymosis.  Petechiae are by definition less than 3 mm.
The term is almost always used in the plural, since a single lesion is seldom noticed or significant.
