So that's start with this question: why do we have different blood types?  Blood types are heritage, just like you inherit your eye color, or your hair texture, so you get a gene from each parent, and that determines what the child's blood type is going to be. There is what formed blood types? There is, there is type A,  Type A,  type B, type AB, and type O. The only difference is what sugar molecular is added to that point. So they are actually kind of generate from each other. So for you to have O, both your parents must be O and only contribute an O. But, if, for example, your father was A and your mother was O, he could actually, one of his parents might have also been O, so he can contribute either an A gene or an O gene, you could be O, cause you get O from him and from your mother, while your sister might be an A. There are some studies that show that the reason that A, B, O and AB have been distributed the way they were was because forces that they think primarily connected to the organism that causes malaria.  It turned out to be that people who had type O were actually able to survive an attack of malaria. It appeared that malaria organism was more readily able to attach to red cells that were type A or type B, and actually kill those patients before they have a chance to reproduce, and people who had type O actually would get sick, but wouldn't die, and had an opportunity to reproduce, and that's how the gene goes forward. And then, if you look at a map of where malaria is now and where the different peoples are, you can see that the type O was follow. There is where there's malaria, A and B has gone to colder climates where malaria wasn't a problem, and then AB was just, you know,  combination of the races. A walk to convey power; a greeting that gets the upper hand; a gesture that can hide a lie, body language can betray us. When a president is under pressure, or a celebrity is in the media glare, look beyond the words, their body language says it all.  This is a certain poise, self-touch gesture, hot spot, or micro-expressions.  In this special, experts will dissect the body, the face and the voice— It’s about our country. —to reveal its hidden meanings, its secrets.  This is a world where what we say is all important. — They said this day would never come. —We hang on every word. —Tomorrow we begin again. Thank you. —But are we getting all the message?  — Older, darker, mean psychopaths, serial killers hang around…  Research has shown that just 7% of human communication is through the actual words.  93% of what we communicate with others is non-verbal.— Bang, bang, bang! — 93%! Think about that. 93%! So it’s our tone of voice, our pitch, our posture, micro-expressions on our face and different gestures that we might use. So we put all the significance on 7% for words. We shouldn’t have really been doing that.  Beyond the words lies a fascinating world of non-verbal communication, the secret world of body language. We are about to watch our one of the world leaders, our sports stars. — Good morning. —We’ll revisit famous figures from recent history.   —Did you kill the President?   — Because people have got to know whether or not their president is a crook, well, but I am not a crook. I've earned everything I’ve got.   We’ll view our celebrities with fresh eyes. We are going to show how people in the public eye try to control the way we perceive them, and how sometimes, despite their best efforts, the truth leaks out.   — Whomever it might be, if the truth is told, then my name will be cleared and I can move on with my life.   If you know what to look for.   — It’s not what you are seeing. It’s what you are not seeing. And you are not seeing an, an anger response.   We are going to equip you with the tools to read those body language giveaway. Naked Cowboy runs for NYC mayor New York City's own naked cowboy, known to locals and thousands of visiting tourists, throws his Stetson into the race for mayor.    【整理】hlr   'You're gonna have to write me in, come November 3rd.'  He's made a career of strumming his guitar and showing some skin, well, quite a lot of skin. Now the man known as the naked cowboy, is hoping to muscle his way into the mayor's office.  'Folks, these are difficult times, and when the going gets tough, you need a cowboy.'  Robert Burck, AKA the naked cowboy, has been a fixture of Time Square for years. Come rain or shine he wears nothing but cowboy boots, a Stetson hat and tight-fitting white briefs. He is now running for mayor of New York city on a platform that promises a whole new level of transparency.  (Hey) 'Folks, nobody has been more exposed to the entire world, out here than yours truly, and you can bet I will bring that same naked truth to running this city as to everything else that I do', Burck has specific plans for the city of New York including giving interest-free micro-loans to a thousand small businesses, opening a wedding chapel in Time Square that would rival Las Vegas and putting renewable energy to work through the use of solar panels and wind farms. He may be a hit with the tourists but it remains to be seen if he can get residence to the ballot box. “I think it is kind of a joke, but it is very novel. No doubt about it, and I’m sure he is gonna get a lot of votes.” “I don't think he stands a chance at all, but I still hope he wins.” Burck's main opponent in November's election will be incumbent Michael Bloomberg. With no strong competitors out here, it's doubtful Bloomberg is shaking in his boots.  Karina Huber, Reuters. Write sb in: to write a person's name on the voting paper and vote for him or her AKA: also known as  Stand a chance: to have the possibility of being successful in doing sth  Shake in one’s boots: to be afraid of; to shake from fear Love your Life However mean your life is,meet it and live it ;do not shun it and call it hard names.It is not so bad as you are.It looks poorest when you are richest.The fault-finder will find faults in paradise.Love your life,poor as it is.You may perhaps have some pleasant,thrilling,glorious hourss,even in a poor-house.The setting sun is reflected from the windows of the alms-house as brightly as from the rich man's abode;the snow melts before its door as early in the spring.I do not see but a quiet mind may live as contentedly there,and have as cheering thoughts,as in a palace.The town's poor seem to me often to live the most independent lives of any.May be they are simply great enough to receive without misgiving.Most think that they are above being supported by the town;but it often happens that they are not above supporting themselves by dishonest means.which should be more disreputable.Cultivate poverty like a garden herb,like sage.Do not trouble yourself much to get new things,whether clothes or friends,Turn the old,return to them.Things do not change;we change.Sell your clothes and keep your thoughts.
