[Q]: Article: There is an English saying: "Laughter is best medicine." Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people's health. Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercises. It increases blood pressure, the heart beating and breathing. It also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial. Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which _ both stress and pain. As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those who are caused by laughter.

[Q]: Article: "We do look very different; we're older. Leo's 38, I'm 37. We were 21 and 22 when we made that film. You know, he's fatter now -- I'm thinner.". So says Kate Winslet, who is thrilled at the 3-D re-release ofTitanicto coincide with the 100th anniversary of the ship's demise. " It happens every time I get on any boat of any kind." She recalls. There are all the people who want her to walk to the front of the ship and re-create her famous pose, arms flung wide. Most people remember the tragedy: The British passenger ship -- said to be unsinkable -- hit an iceberg and sank on April 15, 1912, during its maiden voyage from England to New York City. More than 1,500 people died. But little known is what the world learned from the sinking to prevent future incidents. Probably the greatest deficiency of the Titanic was that she was built 40 years before the widespread use of the wonderful invention radar . Her only defense against icebergs and hidden obstacles was to rely on manned lookouts. On that fateful night the eyesight of trained lookouts only provided 37 seconds of warning before the collision. Traveling at nearly 30 miles an hour the Titanic was moving far too fast to avoid the huge iceberg. The warning did prevent a head-on collision as the officer on the bridge managed to turn the ship slightly. The last ship to send a warning was the California. She was within ten miles of the Titanic during the disaster, but her radio operator went to bed at midnight and never received any of the SOS messages from the Titanic. That was one of the important lessons learned from the catastrophe, the need for 24-hour radio operators on all passenger liners. Another lesson learned was the need for more lifeboats. The Titanic remained afloat for almost three hours and most of the passengers could have been saved with enough lifeboats. 1,500 passengers and workers died in the 28 degree waters of the Atlantic. Out of the tragedy, the sinking did produce some important maritime reforms. The winter travel routes were changed to the south and the Coast Guard began to keep an eye on the location of all icebergs. The new rules for lifeboats were obvious to all. There must be enough lifeboats for everybody on board. The most important lesson learned was that no one would ever again consider a ship unsinkable- no matter how large or how well constructed. Never again would sailors place their faith in a ship above the power of the sea.
