March 21, 2008: let it be forgotten

Let go
.
Let it be forgotten, as a flower is forgotten,
Forgotten as a fire that once was singing gold.
Let it be forgotten forever and ever,
Time is a kind friend, he will make us old.

If anyone asks, say it was forgotten
Long and long ago,
As a flower, as a fire, as a hushed footfall
In a long-forgotten snow.

March 18, 2008: How Well You Know Your Tummy?

9 Surprising Facts About Your Stomach

When it comes to the tummy, experts say myths abound. How much do you really know about your stomach?
By Colette Bouchez
WebMD Feature
.

From those burning, churning feelings that erupt whenever we eat our favorite foods, to the bloating that keeps us from zipping up our jeans, to the gas that can make us the most unpopular person in the elevator, our stomach can be the cause of some major inconveniences, if not some outright health concerns.

Still, experts say most folks know painfully little about how their stomach and their digestive tract operates -- one reason that solving tummy troubles can seem much harder than it has to be.

"There are some very popular misconceptions concerning stomach health, most of which can really lead people astray on how to effectively deal with certain problems," says Mark Moyad, MD, director of preventive and alternative medicine at the University of Michigan Medical Center in Ann Arbor.

Gastroenterologist David Greenwald, MD, agrees. "Sometimes what seems like a complex, difficult or even frightening problem really is a simple one, with a simple solution, if you can separate the myths from the facts," says Greenwald, an associate professor at the Albert Einstein College of Medicine and Montefiore Medical Center in New York City.

To help set the record straight, Greenwald, Moyad, and NYU director of pediatric gastroenterology Joseph Levy, MD, helped WebMD prepare the following gut-busting challenge. Try to separate the myths from the facts to see how much you really know about how to keep your tummy healthy and happy.

1. Myth or Fact: Digestion takes place primarily in the stomach.

Answer: Myth. The major part of the digestive process takes place in the small intestine. The stomach takes in the food, then churns it and breaks it into tiny particles called "chime." The chime are then released in small batches into the small intestine, where most digestion occurs, he says.

Contrary to popular belief, Levy says, foods do not digest in the order they are eaten. "Everything lands in the stomach where it's all churned together, and when it's ready it's released into the small intestines together," he says.

2. Myth or Fact: If you cut down on your food intake, you'll eventually shrink your stomach so you won't be as hungry.

Answer: Myth. Once you are an adult, your stomach pretty much remains the same size -- unless you have surgery to intentionally make it smaller. Eating less won't shrink your stomach, says Moyad, but it can help to reset your "appetite thermostat" so you won't feel as hungry, and it may be easier to stick with your eating plan.

3. Myth or Fact: Thin people have naturally smaller stomachs than people who are heavy.

Answer: Myth. While it may seem hard to believe, the size of the stomach does not correlate with weight or weight control. People who are naturally thin can have the same size or even larger stomachs than people who battle their weight throughout a lifetime. "Weight has nothing to do with the size of the stomach. In fact, even people who have had stomach-reducing surgeries, making their tummy no larger than a walnut, can override the small size and still gain weight," says Levy.

4. Myth or Fact: Exercises like sit-ups or abdominal crunches can reduce the size of your stomach.

Answer: Myth. "No exercise can change the size of an organ, but it can help burn the layers of fat that can accumulate on the outside of your body. Plus it can help tighten the muscles in the abdomen, the area of the body lying just south of the diaphragm, that houses the stomach and many other internal organs," says Moyad.

Interestingly, the part of your "belly fat" that can do you the most harm may actually be the fat you don't see. It resides in the "omentum," a kind of internal sheet that lies over and around your internal organs.

"People who are very overweight often have a lot of fat between their organs internally. In fact, in some instances, the liver can become so packed with fat you can develop a form of hepatitis, and in extreme cases, it can stop functioning altogether," says Levy. The good news: A healthy eating plan can not only help you shed the weight you can see, but also the internal fat layers you don't see.

5. Myth or Fact: Foods that contain insoluble fiber (which does not dissolve in water) cause less gas and bloating than foods with soluble fiber (which does dissolve in water).

Answer: Fact. According to Moyad, most folks are astounded to discover that what they perceived as a "gentler" form of fiber -- the soluble kind found in foods like oat bran, beans, peas, and citrus fruits -- can actually cause more gas and bloating than insoluble fiber, found in foods like whole-wheat bread, wheat cereals, cabbage, beets, and carrots. "It is true," says Moyad. "And the reason is that gas and bloating result from intestinal flora that is needed to digest soluble fiber." Since insoluble fiber is not digested at all -- it goes right through you -- there is no interaction with intestinal flora; consequently, no gas is formed.

One caveat to keep in mind: While insoluble fiber won't give you gas, it can increase the frequency and size of bowel movements.

6. Myth or Fact: One way to reduce acid reflux is to lose as little as 2 to 3 pounds.

Answer: Fact. "The less acid that flows back up into your esophagus, the fewer problems you will have clearing it. And believe it or not, losing just 2 pounds of weight from the abdominal area can make a difference -- and pregnancy is about the best example of this," says Moyad. As the baby grows and pushes against the internal organs, heartburn increases; but once the baby is born and the pressure is relieved, the heartburn is, too. "In much the same way, losing even a little bit of belly fat can provide similar relief.

The really good news: Moyad says most people lose weight in the belly area first, so you should see some positive results on your heartburn within a few weeks after starting a weight loss plan.

7. Myth or Fact: Eating before bed can make you gain weight faster than if you eat the same foods during the day.

Answer: Myth. Most experts agree that we gain weight when we take in more calories than we burn up. And while it seems logical that foods we eat during an active day will burn more quickly and more efficiently than foods we eat right before going to sleep, Moyad says weight gain is not based on a 24-hour clock. "It's the total amount you take in over a period of time compared to how much you burn that determines if you will gain weight. There is no science to show that eating at a specific time of the day can influence weight gain on its own," says Moyad.

That said, Levy reminds us that when we are fatigued or stressed, eating right before bedtime can make digestion more difficult and may cause more gas, bloating, and heartburn. "There is a 'brain' in the gut that helps to make sure that food is moved through the digestive system at the right pace, in the right amount," says Levy. When we are fatigued -- like most of us are at the end of a busy day -- that 'gut brain' is fatigued as well. So, says Levy, there is a decrease in the number of contractions that move food through the system.

8. Myth or Fact: A 200-calorie snack of peanut butter and crackers is more likely to control your appetite than just eating 200 calories' worth of crackers.

Answer: Fact. The reason: "Fats digest much slower than carbohydrates, and they remain in the stomach longer, which means we naturally feel full longer after eating a snack that contains at least some fat," says Levy.

Additionally, Moyad points out that simple carbohydrates (like crackers, bread, or cookies) elicit a quick rise in blood sugar and insulin levels, which subsequently drop just as quickly, causing dramatic shifts in both mood and appetite. "In short, you find yourself edgy and hungry," says Moyad.

9. Myth or Fact: Beans cause everyone to make excess gas, and there's nothing you can do about it.

Answer: Myth ... sort of! Beans are high in a kind of sugar that requires a certain enzyme to properly digest. "Some people have more if it, some people less. And the less you have, the more gas that will be produced during digestion of beans," says Greenwald. What can help: Studies show products like Beano, which add more of the enzyme needed to break down the sugar in beans as well as other traditionally gassy vegetables, can help if taken before you eat. After the fact, you can reduce the gas that forms by taking a product containing simethicone, which, says Greenwald, is a true bubble buster, releasing the surface tension on gas bubbles that form as a result of eating foods that are hard to digest.

March 15, 2008: A Blissful Saturday

It's Saturday again! Who doesn't love Saturday, right?

My Saturday started with surprises found on my balcony:

-- the yellow rose smiling, and it has lovely fragrance too!

-- the red rose doesn't want to be left behind ....

At around 9 am, I left home for my monthly facial and I grabbed caramel machiato and a bite of tuna sandwiches along the way!

The session is scheduled at 10 am . Before it begun, the beautician have a chat with me - to identify my skin condition and what will be the suitable facial for me today. That's one of the things I like about this salon - they don't simply do facial - they will ask about my concern, e.g whether my face is too oily/too dry this month, or whether I've been having more pimples or if I planned to go to the beach they will avoid certain types of facial etc.

A basic facial session started with 2-3 minutes scalp massage, then only the facial begin. After the first mask was applied on the face, another 5-10 minutes scalp massage is given. Then continue with facial - cold steam, followed by face and eyes massage. The second mask is then applied and this is followed by a neck and shoulder massage - about 5-10 minutes - while waiting for the mask to dry. Then followed by the last step of facial. With a soft music on the background (today they played the sound of waves and seagull) and the smell of aromatherapy oil in the room, most of the time I'll fall asleep So, that's my little escapism from the 'real world' - once a month (if I am too busy it will be once every 2 months)!

After facial, it's another routine - browsing at Borders! Today I bought 3 books - 1. Just aromatherapy 2. Malaysia Road Atlas 3. The Rough Guide to Spain .

When I got home, the yellow rose seems fully open now

and a closer look ....

That's my Saturday so far! How's yours?

I'll have to continue with my packing shortly - anybody would like to help?

March 14, 2008: "My insolence"

Who said you need reasons to buy yourself anything - especially after hard week at work? I went to the perfume section at the nearby Mall during lunch break - I always feel relax and 'happy' whenever there's a smell of perfume! Sometimes I just passed by the area without stopping at any perfume counters. But today I stopped at Guerlain counter - which is promoting its new released perfume "My Insolence".

I like the smell:

Top notes: Raspberry

Middle notes: Almond blossom, Jasmine

Base notes: Patchouli, Vanilla, Tonka Bean

And end up bought the 30ml EDT! That's the start of my weekend!

March 03, 2008: ignorant before the heavens of my life

Ignorant before the heavens of my life,
I stand and gaze in wonder. Oh the vastness
of the stars. Their rising and descent. How still.
As if I didn't exist. Do I have any
share in this? Have I somehow dispensed with
their pure effect? Does my blood's ebb and flow
change with their changes? Let me put aside
every desire, every relationship
except this one, so that my heart grows used to
its farthest spaces. Better that it live
fully aware, in the terror of its stars, than
as if protected, soothed by what is near.

March 02, 2008: Tea Drinking

"Tea is drunk to forget the din of the world" (T'ien Yiheng)

~ Care to join me?" ~

[The following article taken from China Daily, 3rd March 2007]

Tea drinking is probably one of the easiest and most pleasant ways to keep fit. In fact, drinking tea has been recognised as a great way to combat weight gain.

Scientific research shows that tea contains polyphenol and dannin, which are good for the body. Polyphenol is a natural antioxidant. It can delay the aging process, and help the body prevent harm from cancer-causing substances such as nitrosamine. Dannin can lower blood fat, prevent the hardening of blood vessels, and help maintain smooth blood circulation, therefore keeping cardiovascular functions normal. Polyphenol can also alleviate symptoms of diabetes, lower blood fat and blood pressure.

One of the most popular teas in China, pu'er, has been proven to lower blood fat significantly. A French doctor once did an experiment, in which he had 20 of his patients with excessive blood fat drink three bowls of pu'er a day. A month later, the patient's blood fat reduced by a quarter.

Green tea is said to prevent cancer, which makes it a wonderful drink for modern people, who sit looking at TV and computer screens all the time. Green tea and oolong tea can moisten the intestines and help replenish vitamins. Black tea and pu'er can warm the stomach, dispel cold, and help with digestion of meat.

But people should drink the right tea, at the right time. Otherwise tea drinking could be harmful.

"Everybody can find his own cup of tea, but if it is not the right tea for him or her, there could be side-effects," said Zhao Yingli, a tea expert based in Beijing.

For example, polyphenol and theine, contained in tea, are beneficial to most people, but not to women during menstruation or pregnancy.

The Chinese consider green tea and oolong cold in nature. Therefore green tea is not suitable for people who have an aversion to the cold, or who are weak in the yin factor of the body, a symptom of which is more than average level of perspiration in hot weather, or after physical exercise. Because of that nature, green tea might cause stomach pain for women during menstruation.

Old people should not drink too much strong green tea either. That is because too much strong green tea could lead to the loss of calcium and cause osteoporosis. Elderly people should drink some black tea, pu'er, or teas with milk.

For people who have insomnia, anxiety, and neurasthenic problems, it is not a good idea to drink green tea or oolong after noon, because it might worsen the problems. A cup of pu'er instead would help with your sleep.

Generally speaking, green tea and oolong are good for summer and autumn. Black tea and pu'er are better choices for winter.

Finally, wash your tea, i.e., tip out your first cup of tea water. This helps to clean the tea and the hot water will dissolve any pesticides. Besides, the first cup is usually tasteless and not a pity to discard.

March 01, 2008: Wet Saturday

[note: picture of raindrops on cactus, at my balcony]

Hi everyone,

My Saturday morning started with quite heavy rain .... which gave me good excuse not to go for morning walk! After webcam chat with Herb and rain stopped at around 10.30 am, I went out to the post office to collect books that Herb sent - due to the size of the parcel the postman can't put in the pigeonhole at my apartment.

Then I proceed to the nearby Mall and have brunch - capuccino and boneless chicken ... something (served with french fries and salad) ..... don't remember the name - not so tasty anyway . But having brunch was not my main agenda. I need to look for a new headset! Been having problem when chatting with Herbie - I can't hear him loud enough, even though the volume has been set to highest! So, I bought myself new Philips headset - if problem remain, then Herb definitely will need to buy new headset

Passed by kitchen section and can't avoid browsing ..... and end up buying something which is not a 'must have' but would be nice to have: kitchen roll/towell holder dispenser and pot cover

One the way out, I dropped by at BodyShop, looking for CocoButter Body Scrub. But unfortunately it has been out of stock for quite sometimes (occording to the salesgirl), so I bought Olive Body Scrub instead, plus the Olive Body Butter.

I also bought the special edition of White Musk EDT which is White Musk Blush EDT - I kind of like its refreshing floral fruity fragrant.

White Musk Blush Eau de Toilette[Sparkling fruity notes and fresh florals combine with velvety musk to create a sensational light-hearted summer fragrance.]

The last item I bought at BodyShop was Grapeseed Glossing Serum for hair - like any other serum, this serum adds gloss and shine to the hair and also helps to mosturize the hair. I never use it before - since my hair grow longer I've been using Loreal Elseve Nutri-Gloss serum. Don't you agree, it is much easier keeping a short hair?

Grapeseed Glossing Serum

So, that's about it! That's what in my shopping bag today!

Love on the Brain
Scientists peeking inside our brains and psyches have more clues than ever about the biology of love -- why we're attracted, why we fall so hard, and what makes us stay.
By Kathleen Doheny
WebMD Feature
Reviewed by Louise Chang, MD
.
.

He's analytical, driven, not very verbal, and not always compassionate.

She's gregarious, intuitive, whimsical, warm, and compassionate.

It's probably a good match, says Helen Fisher, PhD, a cultural anthropologist from Rutgers University and a leading researcher on love, attraction, and romance. One of her findings: Biology matters, and these two people's biology -- their chemical "profiles" -- may complement each other nicely.

In recent years, Fisher and a host of other researchers have been looking deep into our psyche and brains -- helped by high-tech imaging and genetic analysis. They've come up with some intriguing information about what makes us become attracted to someone, what underlies the crazy-in-love feeling, what's up with the transition from butterflies to a more comfortable relationship, and what keeps us attracted.

"It's all much less of a mystery than it was five years ago and certainly 30 years ago," says Arthur Aron, PhD, a professor of psychology at the State University of New York at Stony Brook and another top researcher in the field. The science of the biology of love is relatively new. Research picked up steam in the 1980s, Aron says, and since then experts have made multiple discoveries. Here's a sampling of their findings:

.

The Biology of Love: Biology Matters

When it comes to whom you are attracted to, "your biology plays a role,'' says Fisher, who wrote Why We Love and several other books. It's not only a similar socioeconomic status, level of education and family backgrounds that make people attractive to you, she says, but also hormones -- ones that differ from your own.

We're attracted, Fisher says, to those with a chemical "profile" for estrogen, testosterone, dopamine, and serotonin that's different from our own, yet complements it. For instance, she says, "If you tend to be high estrogen, you will gravitate to the high testosterone type.''

That explains why Mr. Analytical and Driven and Ms. Gregarious and Warm are a match. He's probably a ''high testosterone'' type, Fisher says, and she is probably a "high estrogen" type. "For good Darwinian reasons, they are very complementary," says Fisher. She can likely see many ways of doing things and become indecisive. To the rescue, the analytical man. Likewise, she might inspire more compassion in him. Fisher is working with chemistry.com, an offshoot of match.com, to develop this chemical profile match strategy.

.

The Biology of Love: Your Brain in Love

Love involves three basic brain circuits, according to Fisher. There's the sex drive, which motivates us to seek out partners; romantic love, the in-the-clouds feeling when you first fall in love; and the attachment phase, the comfortable-but-fewer-fireworks stage.

"The sex drive is a very simple drive," Fisher says. "It's simply the craving for sexual gratification, driven largely by testosterone in both men and women."

The three brain systems, however, don't always come into play in any kind of order. They can kick in separately of be intertwined. Or they can trigger each other. For instance: you can have sex with someone but not fall in love, of course; you can be in love with someone with whom you've never had sex.

"Of these three systems, in many respects I think the most powerful one is intense romantic love," Fisher says. With Aron and others, Fisher has used functional magnetic resonance imaging (fMRIs) to examine the brains of people in love and get clues about romantic love.

In one study, 17 people who were newly in love and asked to look at a photo of their beloved showed intense activity in two brain regions associated with reward and motivation -- called the ventral tegmental area and the right caudate nucleus. The findings led Fisher's team to suggest that the crazy-in-love feeling is more a motivation system than an emotion. The report was published in 2005 in The Journal of Comparative Neurology.

"Both the VTA and the caudate nucleus are part of the brain reward system," Fisher says. And the VTA, she says, is a "mother lode" for cells that make dopamine, a brain chemical important for controlling emotional response and the ability to feel pleasure and pain. As dopamine levels in the madly-in-love increase, she says, it accounts for focused attention on the new partner, motivation to get the reward -- and the lover's high.

In this romantic love phase, Fisher says, lovers are motivated to win each other over. Obsessive thinking is part and parcel.

"What we are seeing is activation in the same area as when you expect to receive a large reward," Aron says. It's the same area that "lights up" in cocaine users, he says, as they anticipate using the drug.

"What we think is what's going on when one falls in love is, one perceives incredible opportunities for one's life to be enriched," Aron says. "Perhaps the most important reward for most people is falling in love."

.

The Biology of Love: Smell Counts

Aside from biology and brain activity, body odor is important and help may dictate who we are attracted to and our romantic behavior. "It may be one of the first things that inspires us to say yes or no," says Charles Wysocki, PhD, a researcher at Monell Chemical Senses Center in Philadelphia.

Preference for human body odors is influenced by both gender and sexual orientation, Wysocki and his colleagues found in their research, published in 2005 in Psychological Science. When his study participants of different orientations and genders were asked to choose between distinct odors -- straight men, gay men, straight women, lesbian women -- each picked the odor of a partner of the preferred gender and orientation.

''A person's body odor is determined by a number of factors," Wysocki says," and among them is a set of genes that regulate the immune system." This cluster of genes is called the major histocompatibility complex or MHC. "This MHC confers on an individual an odor print," says Wysocki, citing others' research. And experts have found that a person will seek out a partner with an MHC different than his or her own. "MHC is so variable, no two are alike," Wysocki says.

.

The Biology of Love: The Script Counts

Once you're initially attracted to someone -- helped along by hormones, odor, or other unconscious factors -- what the other person does or doesn't do counts, too. "You become more attracted to people who are attracted to you," Fisher says.

For instance, one research participant told Aron: "I sort of liked this woman and she came over and sat by me." Things developed.

A woman told Aron she was talking to a friend about her piano instructor and the friend said, "You know he likes you." At that moment, the woman told Aron, she realized she had feelings for him, too.

"When people fall in love, that is the most common scenario," Aron says. "We are looking for the opportunity to love and be loved back."

.

The Biology of Love: From Butterflies to Comfortable

After people have been in love a while, the activity in the brain reward areas wanes, Fisher has found in further research. "As the relationship matures, it links in new brain areas associated with emotion," she says. "We aren't exactly sure what is going on, but everyone knows romantic love changes over time."

Still, she says, "chemistry" can persist. "We have started a new study, of those in long-term marriages," she says. Only five people have undergone the fMRI imaging so far, she tells WebMD, but it looks promising for those who yearn for long-term chemistry. "They still show activity in some brain regions associated with romantic love and also with some associated with attachment," Fisher says.

Two other hormones -- oxytocin and vasopressin -- may come into play once you are settling into a more comfortable relationship. At least it's true in small rodents called prairie voles, according to Sue Carter, PhD, a professor of psychiatry at the University of Illinois at Chicago, who has studied the monogamous animals for decades. Both hormones seem important in the animals' attachments to one other vole, she says.

Oxytocin, sometimes called the hormone of love, is plentiful in women in labor and in lactating women and is released by men and women during orgasm. Some human studies have suggested it plays a role in maintaining interpersonal relationships. Vasopressin is released by the pituitary gland.

In voles, at least, Carter says, the hormones seem to play a role in social bonding, and perhaps in reducing fear, making them feel less anxious. So that may play a role in the voles' decision to mate with just one other vole.

.

The Biology of Love: Making it Last

Avoiding boredom is crucial for the health of a relationship, Aron tells WebMD. In a study, he randomly assigned couples to participate in activities both considered highly exciting but moderately pleasant or highly pleasant but moderately exciting.

"The group who did highly exciting but only moderately pleasant activities had a much bigger increase in marital satisfaction," he says. The study was published in the Journal of Personality and Social Psychology.

Meanwhile, another expert is tracking the long-term effect of picking a partner with a different major histocompatibility complex. Martie Haselton, PhD, a psychologist and researcher at the University of California Los Angeles, is working with the web site eharmony.com to track newlyweds, noting the effect of different MHC patterns between partners.

"There is some evidence that fertility is higher in those with dissimilar MHC genes," says Haselton. And children who inherit different MHC genes from each parent are thought to have broader immunity, she says. She also wants to determine if picking someone with different MHC genes than your own bodes well for the relationship long term.

Women in a relationship with a man with very different MHC genes are more sexually responsive to that partner and less likely to be attracted to other men than are women who pair up with a guy with not-so-different MHC genes, says Haselton, citing a study by other researchers published in 2006 in Psychological Science. How that plays out long term will be Haselton's focus as she follows couples for five years or so.

.

The Biology of Love: What Part Chemistry?

So how much of a role does all this chemistry going on in our brains play in all this? "Chemistry isn't quantifiable," Fisher says. In the making of a relationship, she says, several variables come into play -- such as personality, which includes your character and your temperament. "Your character is formed by everything you grew up with," she says. "And your temperament is built by your biology. Together they create who you are."

So it's difficult to put a percent or a number on the role of chemistry in a relationship. And like some of us, it can be fickle. "One moment chemistry rules and the next moment your upbringing will rule," Fisher says. As in: "I'm madly in love with this guy." to "What I am thinking? He's a different religion."

One thing's for sure. There's much more to discover about the biology of love, guaranteeing that relationship scientists will have jobs for years to come.
