Mr. Faugel was convinced that student nervousness had affected their scores; to reduce the anxiety of these students who had already been tested, he gave 22 of them a beta blocker before readministration of the test. Their scores improved significantly. The other 8 students (who did not receive the beta blockers) improved only slightly. Second-time test-takers nationwide had average improvements which were similar to those in Faugel’’s non-beta blocker group. Beta blockers are prescription drugs which have been around for 25 years. These medications, which interfere with the effects of adrenalin, have been used for heart conditions and for minor stress such as stage fright. Now they are used for test anxiety. These drugs seem to help test-takers who have low scores because of test fright, but not those who do not know the material. Since there can be side effects from these beta blockers, physicians are not ready to prescribe them routinely for all test-takers.

If American investors have learned any lesson in the last 25 years, it is to buy shares on the dips. The slide in 2000--2002 may have been longer and deeper than they were used to but normal service was eventually resumed, driving the Dow Jones Industrial Average to a record high on October 1st.
Among American financial commentators, it is almost universally accepted that shares always rise over the long run. And one ought to expect shares (which are risky) to deliver a higher return than risk free assets such as government bonds.
Nevertheless, investors ought also to remember the world’s second largest economy, Japan. Its most popular stock-market average, the Nikkei 225, peaked at 38,915 on the last trading day of the 1980s; this week, nearly 18 years later, it is still only around 17,000, less than half its peak. Buying on the dips did not work either.

Japan bombed Pearl Harbor in 1941. The
United States was mad at the Japanese so they made many Japanese-Americans leave
their homes. They were put in camps with barbed wire around the outside of the
camps. Many Japanese-American young men were called into the army. Some of them joined the US Military Intelligence Service or MIS. The MIS was a secret group that fought the Japanese soldiers. This secret group translated important maps and papers. They questioned Japanese prisoners. Another task they did was to translate diaries written in Japanese. Sometimes Japanese soldiers hid in caves to hide from the Americans. The MIS would try to get the scared soldiers to leave the caves. This was known as "cave flushing." Some of the soldiers would give up and leave the caves. Other Japanese would jump to their deaths.
