--Most Lethal Driving Mistakes--
In an ideal world, drivers would execute every road maneuver with precision and ease. Sadly, we do not live in a never-never land, and not everyone walks away from metal-to-metal mayhem. Truth is that drivers are not created equal. Some are too brash, others too conservative. Some are even downright clueless. The common thread is that they can all turn a pleasant day on the motorway into a surreal nightmare in the blink of an eye.~
To help you stay safe behind the wheel, here's a list of 10 driving behaviors to avoid.
~
Swerving
The No. 1 fatal mistake made by drivers is perhaps the most simple: not staying in their own lane — i.e., running off the road or drifting into the adjacent lane. According to the National Highway Traffic Safety Administration, in 2007, 15,574 people died in crashes where the driver simply couldn't stay in the lane.

Driving While Drowsy
"Driving a vehicle when you are fatigued is as dangerous as driving while impaired by alcohol or drugs," National Transportation Safety Board Acting Chairman Mark V. Rosenker said after a fatal highway accident in 2003 in which a college student who had been awake for the previous 18 hours was driving a carload of fellow students at 5 a.m. According to the NHTSA, in 2007 fatigued driving caused the deaths of 1,404 people, and more traffic fatalities occurred during the hours when most people are accustomed to being asleep (3 a.m. to 6 a.m.) than at any other time of day.

Drinking and Driving
Every 40 minutes someone dies in a drunk-driving accident. (In all 50 states, a blood-alcohol level of 0.08 percent or more is considered illegal, but a little-known fact is that you can be charged with driving while impaired even if you're under the legal limit.) Young drivers are particularly prone to drinking and driving: The 21- to 34-year-old set is responsible for well over half of alcohol-infused fatal crashes. Not surprisingly, the decision to get behind the wheel while intoxicated is made most often at night and on the weekends. According to the NHTSA, 60 percent of drivers who died after dark in 2007 were legally drunk. Alcohol is also a factor in half of pedestrian traffic deaths — both drivers and pedestrians are the culprits.

Overcorrecting
You get panicky when the wheels of your SUV hit the rumble patch on the shoulder of the highway, so you throw the steering wheel in the opposite direction to get the vehicle back on the road. This is a classic example of overcorrecting or oversteering, and it's a particularly perilous maneuver when you're behind the wheel of an SUV driving on the highway at high speeds. Consider it a rollover waiting to happen. More than 4 percent of automobile fatalities a year occur because of drivers overcorrecting.

Speeding
Racing, driving faster than the posted speed limit or simply going too fast for road conditions — i.e., speeding — comprises the second highest cause of death in fatal crashes, according to the NHTSA. Once you hit 55 mph, you're in the danger zone: 30 percent of fatalities occur at 55 or above. The worst-case scenarios invariably involve speeding without wearing a seat belt or a motorcycle helmet. Fatality rates for speeding motorcyclists are shockingly high: In 2007, speeding was a factor in 36 percent of motorcycle fatalities. Of those, 41 percent of drivers and more than half of passengers were not wearing helmets (only 20 states and the District of Columbia require helmets).

Failure to Yield Right of Way
For drivers age 70 and above, failing to yield while merging into traffic is the top cause of crashes. In a recent study by the Insurance Institute for Highway Safety, drivers 80 and older simply fail to see the other vehicle they should be yielding to. Drivers 70 to 79 see the vehicle but misjudge whether they have time to proceed ahead of it. Failure to yield right of way was the fifth leading cause of fatal crashes in 2007.
~
Erratic or Reckless Driving
At its mildest, we're talking about weaving and tailgating; at its most severe, this kind of driving involves steering down the wrong side of the road, exceeding the speed limit by 20 mph or doing more than 80 mph, and worse. Reckless driving can bring fines, jail time — and death. More than 1,850 fatalities in 2007 were the result of erratic or reckless drivers.
~
Running Red Lights
A whopping 75 percent of automobile crashes occur in cities, according to the nonprofit Insurance Research Council. The most common cause of these accidents? Hitting the gas when the light turns red. Of the myriad types of collisions that can result, head-on and side-impact collisions are the most dangerous. NHTSA statistics show that of the 41,059 automobile fatalities in 2007, 54 percent occurred in cars that sustained frontal damage. When you cut it too close while running a light, your front end or another car's front end is impacted. Either way, it's a recipe for a deadly accident.
~
Not Wearing a Seat Belt
Despite the fact that seat belt use is far more prevalent than even a decade ago — not to mention being legally required — 33 percent of people who die in vehicle fatalities failed to buckle up. Without a seat belt, car drivers and passengers put themselves at risk of being ejected from a vehicle, and 76 percent of the time the ejection ends in death.
~
Inattentive Driving
Eating, talking on a cell phone, typing text messages and fumbling with the car stereo all fall under the umbrella of inattentive driving, which was responsible for 4,704 deaths in 2007. Of these bad habits, cell phone use behind the wheel is becoming standard practice, with an estimated 1 million Americans driving and talking on the phone at any given time. With that comes a four-fold increase in the risk of crashing. One example, which caused the NTSB to launch an inquiry, involved an SUV that veered off the left side of the road, jumped the median, flipped and landed on top of a vehicle driving the opposite direction. The driver was trying to negotiate high crosswinds while talking on a handheld phone. Surprisingly, using a hands-free device likely wouldn't have made a difference. "You'd think using a hands-free phone would be less distracting," said Anne McCartt, author of a study published in the British Medical Journal. "But we found that either phone type increased the risk."

--爱一个人就是...--
爱一个人就是，清晨起床时，轻轻一吻；~
爱一个人就是，你赖床不起时，要她拉你起来，当她把手给你的时候，冷不防被你拉到怀里；
~
爱一个人就是，做了她自己都不能下咽的饭菜时，你却津津有味地吃着，一边说女友做的比外面的好吃多了，然后又偷偷地再吃别的东西；
~
爱一个人就是，她生气时，你绕着她左三圈右三圈的转：你别生气了，你看你看，我都急得团团转了；
~
爱一个人就是，她没胃口，不想吃饭时，你一边大声地骂着她，一边往她碗里夹她最喜欢的菜；
~
爱一个人就是，当她身体不好，要坚持吃药，而她老是很大意的将药丢到一边，你看到后对她狠狠地说：以后要是你痛可别叫我，我是不会理你的。到了她痛的时候你看她时比她更痛的眼神；
~
爱一个人就是，自己吃东西的时候，不在意的就送到她的嘴边，她也不在意的吃上一口；
~
爱一个人就是，出差在外，每天给她的一个很平常的电话；
~
爱一个人就是，你（她）在外面无论遇到什么好玩的、好看的、好吃的都会在心里想到：要是她（你）在有多好；
~
爱一个人就是，无论把她带到何种场合，你都自豪的介绍：这是我女友；
~
爱一个人就是，永远用爱心对她，不刻意的为她做很多的事，但每一件都充满浓浓的爱意；
~
爱一个人就是，相信她的全部，也尊重她的全部；
~
爱一个人就是，两个人互相依赖，互相习惯，习惯于生活中有彼此的存在，习惯于对方的优点和缺点，习惯于空气中有他气息；
~
爱一个人其实就是平凡，爱到平凡才是真。
~
~
爱是互相包容理解，不是牵拌束缚；爱是为了能使互相生活的更加美好，不是为了彼此猜疑；

--Dissociative identity disorder (DID)--
Dissociative identity disorder (DID), as defined by the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM), is a psychiatric diagnosis that describes a condition in which a single person displays multiple distinct identities or personalities (known as alter egos or alters), each with its own pattern of perceiving and interacting with the environment. The diagnosis requires that at least two personalities routinely take control of the individual's behavior with an associated memory loss that goes beyond normal forgetfulness; in addition, symptoms cannot be due to drug use or medical condition. Earlier versions of the DSM named the condition multiple personality disorder (MPD), and the term is still used by the ICD-10.~
There is a great deal of controversy surrounding the topic. There are many commonly disputed points about DID. These viewpoints critical of DID can be quite varied, with some taking the position that DID does not actually exist as a valid medical diagnosis, and others who think that DID may exist but is either always or usually an adverse side effect of therapy. DID diagnoses appear to be almost entirely confined to the North American continent, adding to the possibility that DID may not be a legitimate diagnosis.
