Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．

       Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．

       By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group        C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．

       “The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．

       “Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．

Why did the scientists carry on the new research?

       A．To find out if laughter was good to health．

       B．To discover the best medicine to cure diabetes．

       C．Because the number of diabetic patients is the largest in the world．

       D．Because diabetic patients need more laughter than other patients．

       B．the level of the hormones epinephrine stays the same in both groups

Never argue with one's own understanding.

The whisper of intelligence is always there, whatever you do.

If you create a time lag (隔绝层) between the whisper of intelligence and understanding in you and your action, then you are preventing the brain from growing into a new size. When you argue with intelligence, when you postpone acting according to understanding then there is confusion, the brain gets confused.

The voice of understanding, the voice of intelligence has insecurity about it. How do you know that it is the right thing?

So we tend to ignore it. Instead we accept authority. We obey.

But the brain cannot be orderly, competent, accurate and precise if you do not listen to it, if you have no respect. We are so busy with the outside world and its force that the world that is inside us does not command that respect and reverence (敬重), that care and concern from us.

So one has to be a disciple (信徒) of one's own understanding, and look upon that understanding as the master.

Sometimes one may commit a mistake, it might be the whim (念头) of the ego and we might mistake the whim, the wish of the ego for the voice of silence and intelligence, but that we have to discover. Unless you commit mistakes, how do you learn to discriminate between the false and the true? In learning there is bound to be a little insecurity, a possibility of committing mistakes. Why should one be terribly afraid of committing mistakes?

So instead of accepting the authority of habits and conditionings, while one is moving one watches, and when there is a suggestion, do not neglect, ignore, or insult the whisper from within and from one's own intelligence.

Nothing can spoil a vacation quicker than losing your money or credit cards. A few simple steps before you head out of the door can help protect your cash, card and personal information while you’re traveling.
Paul Stephens, a policy analyst San Diego, notes that people spend a lot of time planning their trips, from buying guidebooks to finding just the right beach outfits（装备）.“But their eyes glaze（呆滞） over when the subject of keeping money safe comes up,” he said.
“Why not take a few minutes to do something that could probably save your vacation?” Stephens asked．“In most cases, they can go on your to-do list with‘ buy travel bags’ and everything else,” he added.
The top recommendation is to clean your wallet. Remove unnecessary credit cards and any other unneeded documents that could compromise（危及...的安全）your identity if lost or stolen while you’re on vocation.
Then make a photocopy of the cards you’ve decided to take along and keep it in a secure location with you（not in your wallet）or leave it with a trusted relative or friend back home. Then you will know who you need to contact and how to reach it if your wallet is missing.
“Travelers should never leave their wallets or any identifying documents in their hotel room when they’re not there,” he said.” Choose a hotel with a safe to keep your valuable things in. Or keep your wallet and documents with you at all times. ”
