A bone is a rigid organ that constitutes part of the vertebrate skeleton.

Bones support and protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

Bones come in a variety of shapes and sizes and have a complex internal and external structure.

They are lightweight yet strong and hard, and serve multiple functions.

A Lifetime of Learning is the third full-length album by Better Luck Next Time.

It was released in Japan on December 26, 2009, and on May 3, 2011, in the United States.

The Japanese edition includes the studio version of "Truth for Two" as a bonus track, whereas the American version features it while still in pre-production.

The album was released as a "Special Edition" in America, containing many pre-production versions of the albums' tracks.

It also features early demo versions of songs from their previous two releases, Third Time's A Charm and Start From Skratch.

A previously unreleased track called "In the End" appears on the American version in pre-production form.

The track order is also different between the two versions.

Courage (also called bravery or valour) is the choice and willingness to confront agony, pain, danger, uncertainty, or intimidation.

Physical courage is bravery in the face of physical pain, hardship, death or threat of death, while moral courage is the ability to act rightly in the face of popular opposition, shame, scandal, discouragement, or personal loss.

A community is a small or large social unit (a group of people) who have something in common, such as norms, religion, values, or identity.

Often - but not always - communities share a sense of place that is situated in a given geographical area (e.g. a country, village, town, or neighborhood).

Durable relations that extend beyond immediate genealogical ties also define a sense of community.

People tend to define those social ties as important to their identity, practice, and roles in social institutions like family, home, work, government, society, or humanity, at large.

Although communities are usually small relative to personal social ties (micro-level), "community" may also refer to large group affiliations (or macro-level), such as national communities, international communities, and virtual communities.
