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.
Olives have been cultivated in parts of the Mediterraneanâincluding Crete and Syriaâfor at least 5,000 years. In addition, there is carbon-dating evidence of olive tree presence in Spain as many as 6,000â8,000 years ago. This ancient and legendary tree was also native to parts of Asia and Africa.
