salam..
i just want to share about an article that i search in the http://en.wikipedia.org..
it's about stress..
stress mean a biological term which refers to the consequences of the failure of a human or animal body to respond appropriately to emotional or physical threats to the organism, whether actual or imagined.
for my opinion,stress can make someone be an abnormal person like an usual. it's will force someone doing the false or even the bad thing that he/she never do such as kill herself/himself.this is we call negative stress. sometimes,stress also make the people change in their attitude from bad to better..this is we call the positive stress..
for me,actually it's depend to the person as they can choose another one of the type of the stress..
so,as the final exam is around the corner,i would like to advise all my friend-don't be stress and always be cool.study with hard and smart without stress..
that's all,thank you..

Easy-to-swallow Advice
i)There are no magic bullet. Good as they can be, supplements can only be just supplements. When it comes to strengthening your immune system, they’re never a replacement for a healthy diet, exercise, stress-reducing routines and good sleep habits.
ii)Consults a doctor with an interest in nutrition or a qualified nutritionist. Avoid advice from unqualified people, especially if large if large doses of supplements are recommended. If taken in excess, some supplements do more harm than good.
iii)It’s doesn’t pay to take pills you don’t need. If you’re taking a specific reason and you don’t see an improvement after a month or two, or if you symptoms have worsened, consult your doctor before continuing to use it. Natural health practitioners are listed on the web site of the Australian Traditional Medicine Society.

Buying Herbal Supplements
1)Note the form the herb listed on the package.when possible,select a standardised extract.Standardisation ensures that each dosage contains the same percentage of active compounds.(even plants of the same species can vary greatly in the quantity and strength of these compounds.only with standardisation can you be sure you're getting the right amount).otherwise,choose a product labelled 'whole herb'.these contain all of the herb's distinct compounds in the ratio nature provided.
2)Check the expiry or best-used-by date.discard the product if that date has passed.
3)Read any health warnings,cautions and contraindications to be certain that the herb is appropriate for you.herbal supplements in Australia are regulated by the Therapeutic Goods Administration.products are classified as 'R',registered,if they have shown proven effectiveness,or 'L',listed,if they are safe but have not show proven effectiveness for the therapeutic claims made.in New Zealand anything promoted as a health product must be cleared for safety and efficacy by the Health Minister before going on sale.

Some tips to help your first foray into yoga go smoothly.
1)Talk to you doctor.certain medical conditions may rule out specific poses.if you have high blood pressure,glaucoma,a history of retinal detachment,or heart disease,for instance,your doctor may advise you not to do hand,head or shoulder stands.because they tend to increase blood flow to the head,such positions could aggravate any of those conditions.
2)Fit the class to your abilities.talk to the teacher before signing up to alert him or her to your newcomer status and make sure you'll be comfortable with the level of the class.
3)Wear comfortable clothes.good choices are bike shorts,stretchy leggings,or tight and a T-shirt.you must be able to move easily and be able to see you body.work bare-foot,but take your own mat if you prefer.
4)Don't overdo it.push yourself,but don't be talked into anything that feels overly difficult.a good yoga teacher will guide-rather than force-your body into the correct form.

What's Your Napping Style?
What's Your Napping Style?
1)Replacement sleepers nap to get a much-needed energy boost,because they don't sleep enough at night.
2)Split sleepers regularly divide their total sleeping time into two periods-midday and night.not surprisingly,this is especially common among night or split-shift workers.
3)Long sleepers simply enjoy more than a 'full' night's sleep.a famous example was Winston Churchill,who napped every day,even at the height of his wartime responsibilities.'Nature had not intended man to work from eight in the morning until midnight,without the refreshment of blessed oblivion,which,even if it last only 2o minutes,is sufficient to renew all vital forces,'he wrote.
4)Prophylactic sleepers nap to store up for a planned deficit because they may have work obligations,or plan to travel later or have a night out.

why we sleep?
Salam..you know why we sleep? let's check up..There are a few theories as to why we need so much sleep. One idea is that sleep is restorative to the body, giving it an opportunity to rest. But if rest is the goal, why does our brain remain hard at work? It's possible that while we sleep, the brain is practicing and running problem-solving drills before completing actions in the real world. There are several studies that show that learning can't take place without sleep to reinforce the knowledge [source: Schaffer].
Some of these studies may have real implications for students. One researcher claims that it would be better for students to review information until they were tired, then slept, as opposed to pulling an all-nighter [source: BBC]. Some schools have changed the time of that first bell so that middle and high school students can get a little more snooze time [source: Boyce, Brink]

What causes the smell after rain?
Salam..today i read some article What causes the smell after rain?
Most people notice a distinctive smell in the air after it rains. It's frequently linked with spring, as the smell of fresh cut grass is associated with summer. You'll find it in a lot of poetry and also on many inspirational lists of things to be happy about. But what causes it?
As it turns out, the smells people associate with rainstorms can be caused by a number of things. One of the more pleasant rain smells, the one we often notice in the woods, is actually caused by bacteria! Actinomycetes, a type of filamentous bacteria, grow in soil when conditions are damp and warm. When the soil dries out, the bacteria produces spores in the soil. The wetness and force of rainfall kick these tiny spores up into the air where the moisture after a rain acts as an aerosol (just like an aerosol air freshener). The moist air easily carries the spores to us so we breathe them in. These spores have a distinctive, earthy smell we often associate with rainfall. The bacteria is extremely common and can be found in areas all over the world, which accounts for the universality of this sweet "after-the-rain" smell. Since the bacteria thrives in moist soil but releases the spores once the soil dries out, the smell is most acute after a rain that follows a dry spell, although you'll notice it to some degree after most rainstorms.
Another sort of smell is caused by the acidity of rain. Because of chemicals in the atmosphere, rainwater tends to be somewhat acidic, especially in urban environments. When it comes in contact with organic debris or chemicals on the ground, it can cause some particularly aromatic reactions. It breaks apart soil and releases minerals trapped inside, and it reacts with chemicals, such as gasoline, giving them a stronger smell. These reactions generally produce more unpleasant smells than bacteria spores, which is why the after-the-rain smell isn't always a good one. Like the smell caused by the bacteria spores, the smell of chemical reactions is most noticeable when it rains following a dry spell. This is because once the chemicals on the ground have been diluted by one downpour, they don't have the same reaction with the rainwater.
that's all.
