Forbes magazine began reporting on Beyonce's earnings in 2008, calculating that the $80 million earned between June 2007 to June 2008, for her music, tour, films and clothing line made her the world's best-paid music personality at the time, above Madonna and Celine Dion. They placed her fourth on the Celebrity 100 list in 2009 and ninth on the "Most Powerful Women in the World" list in 2010. The following year, Forbes placed her eighth on the "Best-Paid Celebrities Under 30" list, having earned $35 million in the past year for her clothing line and endorsement deals. In 2012, Forbes placed Beyonce at number 16 on the Celebrity 100 list, twelve places lower than three years ago yet still having earned $40 million in the past year for her album 4, clothing line and endorsement deals. In the same year, Beyonce and Jay Z placed at number one on the "World's Highest-Paid Celebrity Couples", for collectively earning $78 million. The couple made it into the previous year's Guinness World Records as the "highest-earning power couple" for collectively earning $122 million in 2009. For the years 2009 to 2011, Beyonce earned an average of $70 million per year, and earned $40 million in 2012. In 2013, Beyonce's endorsements of Pepsi and H&M made her and Jay Z the world's first billion dollar couple in the music industry. That year, Beyonce was published as the fourth most-powerful celebrity in the Forbes rankings. MTV estimated that by the end of 2014, Beyonce would become the highest-paid black musician in history; she succeeded to do so in April 2014. In June 2014, Beyonce ranked at #1 on the Forbes Celebrity 100 list, earning an estimated $115 million throughout June 2013 June 2014. This in turn was the first time she had topped the Celebrity 100 list as well as being her highest yearly earnings to date. As of May 2015, her net worth is estimated to be $250 million.

Much of the current knowledge of memory has come from studying memory disorders, particularly amnesia. Loss of memory is known as amnesia. Amnesia can result from extensive damage to: (a) the regions of the medial temporal lobe, such as the hippocampus, dentate gyrus, subiculum, amygdala, the parahippocampal, entorhinal, and perirhinal cortices or the (b) midline diencephalic region, specifically the dorsomedial nucleus of the thalamus and the mammillary bodies of the hypothalamus. There are many sorts of amnesia, and by studying their different forms, it has become possible to observe apparent defects in individual sub-systems of the brain's memory systems, and thus hypothesize their function in the normally working brain. Other neurological disorders such as Alzheimer's disease and Parkinson's disease can also affect memory and cognition. Hyperthymesia, or hyperthymesic syndrome, is a disorder that affects an individual's autobiographical memory, essentially meaning that they cannot forget small details that otherwise would not be stored. Korsakoff's syndrome, also known as Korsakoff's psychosis, amnesic-confabulatory syndrome, is an organic brain disease that adversely affects memory by widespread loss or shrinkage of neurons within the prefrontal cortex.
Is amnesia only seen in one form?

After the Dalai Lama's government fled to Dharamsala, India, during the 1959 Tibetan Rebellion, it established a rival government-in-exile. Afterwards, the Central People's Government in Beijing renounced the agreement and began implementation of the halted social and political reforms. During the Great Leap Forward, between 200,000 and 1,000,000 Tibetans died, and approximately 6,000 monasteries were destroyed during the Cultural Revolution. In 1962 China and India fought a brief war over the disputed South Tibet and Aksai Chin regions. Although China won the war, Chinese troops withdrew north of the McMahon Line, effectively ceding South Tibet to India.
