Definition of Brain Drain. Brain drain can be described as the process in which a country loses its most educated and talented workers to other countries through migration. This trend is considered a problem, because the most highly skilled and competent individuals leave the country, and contribute their expertise to the economy of other countries.
Olives, like many other kinds of produce such as potatoes and sour cherries, just aren't something that you eat raw. Unprocessed, straight off the tree, they are bitter, very bitter, and the green ones even more so than ones which have fully ripened to black.
Olive trees are some of the oldest trees ever harvested by humans, a practice that dates back more than 8,000 years. Today, olives are grown both for their oil (but that's another article...or a book!) and their fruit. The trees themselves thrive in warm, subtropical zones, especially in sea air and rocky soil. Native to Syria and Asia Minor, the first olives were picked from low shrubs.
