You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air. <sep>What happens when less heat reaches the surface of your skin?<sep>Cools the body
No

The cute red ball rolled over to the blue ball and said hello. The blue ball was scared and went to cry to the green ball. The green ball laughed at the blue ball. Then the green ball told the orange ball that blue ball was stupid. Most felt this was not good to do and so they punished the green ball by taking away all his air. From that day on everyone saw the air-less green ball and knew that they could not do or say any bad things. This is how the trouble started. The purple ball used the fear of everyone to become the leader that they all feared. The purple ball was mean to everyone. Until one day the red ball spoke up and got all the other colored balls together and they took the air from the purple ball and put it in the green ball. Sadly, the green ball had been without air for too long and was dead. <sep>Why was everyone afraid to say bad things?<sep>Because they saw the green was airless because he said the blue ball was stupid
No

This week, we've been treated to the increasingly familiar sight of former NBA star and provocateur Dennis Rodman attending events in Pyongyang, North Korea. It's his fourth trip in less than 12 months. On Tuesday, an angry Rodman defended his visit in a CNN interview straight from Pyongyang, at one point saying to "New Day" anchor Chris Cuomo, "I don't give a rat's ass what the hell you think ..." in response to question about Kenneth Bae, an American detained in North Korea. When will we tire of this circus? In case you don't watch cable news, you might miss that the media really loves this kind of thing. No story about North Korea is too weird to go unreported, even if there is no real information to disseminate. Recall the recent rumor that Kim Jong Un's uncle was executed by being fed to hungry dogs, which most likely was started as satire on Chinese social media but was at first reported widely in the media (CNN was unable to confirm and did not report the story). In media discourse, North Korea is the classic enemy. The regime's injustices, quirks and dysfunctions are reassuring to Americans that their own country is just the opposite: Normal, well-functioning, a land of peace and liberty. But add in Rodman to the North Korea story, and it's bound to produce eye-popping headlines: The Weird American Athlete Goes to Weird Country story is just too easy not to cover. Rodman himself seems to be thriving on finding a strange smidgen of relevance through his visits to North Korea (and perhaps a Paddy Power paycheck). Though often described as quite shy, he has always enjoyed challenging the values of Middle America. North Korea is providing him a new avenue to be in the spotlight. The most passive player in this tragicomedy is Rodman's home country, the United States. The U.S. State Department has deployed the rhetorical equivalent of an embarrassed teenager whose dad has shown up to dance at his prom. Something along the lines of "this has nothing to do with us" is what the State Department has said with every one of Rodman's trip. Last winter,the State Department criticized Rodman's timing as it followed a nuclear test and rocket launch. <sep>How many trips has Dennis Rodman made to North Korea in under 12 months?<sep>3
