When you return, declare all food, meat, fruits, plants, seeds, wooden souvenirs, animal or plant materials. Australia has strict quarantine laws and tough on-the-spot fines. Every piece of luggage is now screened or X-rayed. If you fail to declare any quarantine items, or if you make a false declaration, you will get caught. In addition to on-the-spot fines, you could be accused and fined more than $60, 000 and you may risk 10 years in prison. All international mail is also screened. Some products may require treatment to make them safe. Items that are restricted because of the risk of pests and diseases will be seized and destroyed by the Australian Quarantine and Inspection Service(AQIS). In many cases, the goods you declare will be returned to you after inspection. However, any item that presents a quarantine risk will be withheld . You will be given a range of options for each item depending on the quarantine risk: Treating the item to make it safe; Holding the item until an import permit is presented*; * Re-exporting the item; Destroying the item. Those treatments with the sign "*" are subject to fees. Further information: For more detailed information about bringing in food, animals, plants, animal or plant materials, call the AQIS at 1800-020-504.

Article: A terrible competition is going on in England, with billions of dollars and hundreds of lives at risk. OK, that's not true. But competitors from around the world gathered on Thursday for the annual competition to compete for the world's biggest person who tells lies. Each participant is given up to five minutes to make up the best _ in the contest, which was founded in honor of 19th-century Bridge Inn landlord Will Ritson, who was reportedly famous for his lies. Competitors gather at the Bridge Inn every year for the competition, a small pub in northwestern England. Anyone but lawyers and politicians can take part in the competition. A study found that nearly all lies are detectable through visible facial muscle reactions in the person telling a lie. "Thus, while interpersonal cheat often is highly successful, signs of hidden emotional states are communicated clearly to the informed observer," the study concluded. A churchman of Carlisle reportedly holds what may be the greatest lie of all time in the competition, simply stating, "I have never told a lie in my life." In 2003, Abrie Krueger from South Africa became the first one to win the competition. In 2006, comedian Sue Perkins became the first female to win the competition, telling a tale about people riding camels to work as a result of climate change.
Answer: He intends to talk about a contest.

Article: Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure. Dr. Scott Small is a professor of neurology at Columbia University in new York City He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memorytests. The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four .year study involving 18,000 adults. This study will use flavones capsules The study subjects will be divided into two groups and will take two pills per day. The capsules used will all Look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo Dr. Manson says it's not necessary for people to start eating more chocolate, because 3 person would have to eat a huge amount of chocolate to get the same level of flavones given to the Lest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarity, Dr. says a cocoa-based flavones extract may be developed in the future But he says that more studies are needed to see how much flavones is good for our health
