A picture worth a thousand words
GAMBAR MEMBERI SERIBU SATU CHERITERA
Gambar yang amat menyentuh hati….seorang anak yatim melukis gambar "mama"nya dan tidur bersama lukisan itu.
sekiranya kita ternampak anak-anak yatim berikanlah mereka bukan hanya barangan material seperti makanan, tapi beri mereka pelukan dan ciuman yang jarang mereka dapat tetapi amat diperlukan dan dirindui....

Why Is the Ocean Salty?
By Anne Marie Helmenstine, Ph.D., About.com Guide
Question: Why Is the Ocean Salty?
Have you ever wondered why the ocean is salty? Have you wondered why lakes might not be salty? Here's a look at what makes the ocean salty and why other bodies of water have a different chemical composition.
Answer: It's really easy to understand why the ocean is salty. The oceans have been around a very long time, so some of the salts were added to the water at a time when gases and lava were spewing from increased volcanic activity. The carbon dioxide dissolved in water from the atmosphere forms weak carbonic acid which dissolves minerals. When these minerals dissolve, they form ions, which make the water salty. While water evaporates from the ocean, the salt gets left behind. Also, rivers drain into the oceans, bringing in additional ions from rock that was eroded by rainwater and streams.
The saltiness of the ocean, or its salinity, is fairly stable at about 35 parts per thousand. To give you a sense of how much salt that is, it is estimated that if you took all the salt out of the ocean and spread it over the land, the salt would form a layer more than 500 feet (166 m) deep! You might think the ocean would become increasingly salty over time, but part of the reason it does not is because many of the ions in the ocean are taken in by the organisms that live in the ocean. Another factor may be the formation of new minerals.
So, lakes get water from streams and rivers. Lakes are in contact with the ground. Why aren't they salty? Well, some are! Think of the Great Salt Lake and the Dead Sea. Other lakes, such as the Great Lakes, are filled with water that contains many minerals, yet doesn't taste salty. Why is this? Partly it is because water tastes salty if it contains sodium ions and chloride ions. If the minerals associated with a lake don't contain much sodium, the water won't be very salty. Another reason lakes tend not to be salty is because water often leaves lakes to continue its trip toward the sea. According to an article at Science Daily, a drop of water and its associated ions will remain in one of the Great Lakes for around 200 years. On the other hand, a water droplet and its salts may remain in the ocean for 100-200 million years.

STROKE IDENTIFICATION
During a party, a friend stumbled and took a little fall - she assured everyone that she was fine and just tripped over a brick because of her new shoes. (they offered to call ambulance)
They got her cleaned up and got her a new plate of food - while she appeared a bit shaken up, Ingrid went about enjoying herself the rest of the evening. Ingrid's husband called later telling everyone that his wife had been taken to the hospital - at 6:00pm , Ingrid passed away. She had suffered a stroke at the party . Had they known how to identify the signs of a stroke, perhaps Ingrid would be with us today.
Some don't die. They end up in a helpless, hopeless condition instead. It only takes a minute to read this...
STROKE IDENTIFICATION:
A neurologist says that if he can get to a stroke victim within 3 hours he can totally reverse the effects of a stroke...totally. He said the trick was getting a stroke recognized, diagnosed, and then getting the patient medically cared for within 3 hours, which is tough.
RECOGNIZING A STROKE
Remember the '3' steps, STR . Read and Learn!
Sometimes symptoms of a stroke are difficult to identify. Unfortunately, the lack of awareness spells disaster.
The stroke victim may suffer severe brain damage when people nearby fail to recognize the symptoms of a stroke.
Now doctors say a bystander can recognize a stroke by asking three simple questions :
S * Ask the individual to SMILE .
T * = TALK. Ask the person to SPEAK A SIMPLE SENTENCE (Coherently) (eg 'It is sunny out today').
R * Ask him or her to RAISE BOTH ARMS .
If he or she has trouble with ANY ONE of these tasks, call the ambulance and describe the symptoms to the dispatcher.
NOTE : Another 'sign' of a stroke is
1. Ask the person to 'stick' out their tongue.
2. If the tongue is 'crooked', if it goes to one side or the other that is also an indication of a stroke.
A prominent cardiologist says if everyone who gets this status shares it; you can bet that at least one life will be saved.
And it could be your own.
