In recent years, doctors have been puzzled by the very rapid spread of antibiotic-resistant types of bacteria. Now, researchers trying to find out how bacteria travel so quickly from one area to another have found one possible cause: money. To be more exact, paper money. The researchers, who work at an Air Force base in the United State, described dollar bills as "bacteria farms."
There is nothing particularly suprising about the results. Anything that is handled by many people and never washed is bound to be dirty. What is suprising is the great variety of bacteria on money. Almost a hundred different types of bacteria were found on the bills, which had been randomly collected from grocery stores in the area.
Of these bacteria, allmost 95% could cause illness in humans. On almost 10% of the bills were found some particularly dangerous types of bacteria--klebsiella, which causes pneumonia, and staphylococcus, which causes food poisoning.
As you might expect, the dirtiest money was US$1 bills, whereas US$50 bills were the cleanest. These figures would be probably be similar for any country's paper money. Before you panic and decide to burn all your money, remember what the scientists say: all the bacteria found on the bills are also commonly found in the human body, where they don't always cause health problems.
Dreams and their meanings have been a source of fascination for humans for over 5,000 years. The ancient Egyptians believed that dreams foretold the future. Some tribes in the South Pacific regards dreams as having the power to heak physical problems. Sigmund Freud, whose book The Interpretation of Dreams was published in 1900, thought that dreams revealed our subconscious.
Whatever the purpose of dreams, we now know that we dream for only a small part of the time that we are asleeo. Most of the time we are on slow-wave sleep. Dreaming, however, takes place during the short periods of sleep known as REM sleep.
During REM sleep, our brain activity is similar to that when we are awake, but our body cannot move freely. Each night, as long as we are undisturbed, we have four periods of REM sleep. The first comes about ninety minutes after we fall asleep. The second and third occur in the middle of the night and the last one just before we wake up. If we remember any dreams at all, they are from this last period.
People never get tired of talking about their dreams and about what they might mean. Dozens of books have been writen on the subject. While they might disagree on the details, these books contain some similar beliefs.
If, for example, you dream about catching fish, then you will be lucky. If your dream contains ants, then the next day there will be many small things that annoy you. A dream of an ape means that someone close to you will get sick. Dreams about apples are good, especially if the apples are ripe. On the other hand, dreams of vegebtables means that bad luck is coming.
Dreams of flying are very common. Most people think that this means that the dreamer feels trapped and wants to be free. However, according to the "experts", dreams of flight can have many different explanations. If you dream about flying through space, then it suggests that a war or some major disaster is coming. If you dream about seeing the sun when you fly, then it suggests that you should stop worrying so much.
Some scientists believe that dreams are nothing but "random nerve-cell activity". This may be true; still, it is fun to think that an activity shared by all mammals may have deeper meanings. And just to be on the safe side, if you dream that you are flying high above a lot of ants, with a giant tomato in your hand, you'd better stay in bed the next day.

One way to encourage positive thinking is to bombard your mind with positive thought intensions. For example, telling yourself 'I feel good and I am giving up smoking', is far more positive than the negative 'I am not going to smole anymore'. You can reinforce the message by writing out positive thoughts and placing them at eye level around the workplace and home. If you have made a conscious decision not to get tense during the day, put up positive messages such as 'I am feeling pleasantly relaxed', and 'I am going to sleep well tonight'. Repeating these positive phrases to yourself even when stressed, helps to replace negative 'what's the use?' self-sabotage thoughts.
After torrential rain, floodwaters were two metres high. Mrs Boudreaux was sitting on her roof with her neighbour, Mrs Thibodaux, wait ing for help to come.
Mrs Thibodaux spied a lone cap floating near the house, moving back and forth slowly but steadily. "Do you see the cap?" she asked Mrs Boudreaux.
"Yes, that's my husband," Mrs Boudreaux replied. "I told him he was going to cut the grass today come hell or high water."

A married couple , both 60 years old, were celebrating their thirty-fifth wedding anniversary. A fairy appeared to congrulate them and grant them each one wish.
The wife wanted to see the world. The fairy waved her wand and poof!--the wife had tickets in her hand for a world cruise.
Next, the fairy asked the husband what he wanted. He said, "I wish I had a wife 30 years younger than me." The fairy waved her wand and poof!--he was 90 --Heather Rowland
--Dinner with a bang
Soon you may be able to judge the quality of a restairant by the size of the explosions coming from its kitchen. Agricultural researchers in the U.s. have discovered that if you want to make meat tender, the best way is to blow it up.
Until now, if a cook wanted to soften steak, his only choice was to hit it with a special hammer. Hit it long and hard. This works fine with small pieces, but if there is a lot of meat to soften, it can be very time-consuming, not to mention tiring.
A new method involves putting meat on a steel plate at the bottom of a water-filled barrel. A bit of dynamite is then put inside the barrel and exploded. The water transmits the explosive shoock wave through the meat breaking down the muscle and connective tissue that make meat tough.
Amazingly, the explosion not only softens the meat but also makes it cleaner--by killing off bacteria. Tests show that bacteria levels are reduced by the explosion to only one-thousandth of their original level.
The only problem left for restaurants is how to keep the loud explosions from scaring away their customers.
-Eat a balanced diet. --An inadequate diet will deplete your body of the resources it needs to deal with life's demands.
-Ensure you get adequate sleep--Sleep deprivation can cause stress, which in turn can cause insomnia.
-Exercise regularly--Physical exercise helps to relieve tension, and to build up your general health, making you more resistant to illness and disease.
-Learn to relax--Make time for walking or gardening. You may find it easier to learn to relax by practising techniques such as meditation or yoga in a group.
-Practise visualitation techniques--Imagining yourself in a pleasant setting can help promote feelings of relaxation. Visualising a positive outcome to the problem that is causing stress can also help to reduce stress-related symptoms.
-Think positively--Try to look at experiences that induce feelings of anger and depression in a positive way.
