A typical day at work for Cesar Millan includes taking a four-hour jog with 40 dogs, large and small, young and old, and none of them on leashes （缰绳）．Although most of these dogs belong to him, the rest are troubled dogs sent to Millan to learn good behaviour．Obviously, Millan has a special gift for working with these animals．

Growing up on a farm in Mexico, Millan knew he would work with dogs．His first job, at age 15, was helping a veterinarian （兽医）．He was so good at calming scared dogs and handling all kinds of situations that people started calling him 'the dog boy．’ Since then, he has built a rewarding career around his favourite animal．

Studying dogs on the farm where he grew up, Millan realised they need a lot of exercise to be calm．He explains his approach; "Exercise and discipline （纪律） first, and then affection!" He says a lot of people get it wrong because they do not realise what dogs really need．Millan does not only train dogs, he also trains owners to understand that their pets need rules．He has helped celebrities like Oprah Winfrey and Will Smith and everyday people too．

At his Dog Psychology Centre in Los Angeles, California, Millan also works with dogs whose dangerous behaviour has prevented them from finding homes．He teaches them to be loving gentle pets．Viewers can actually see the change in dogs with troublesome behaviour on Millan's TV show The Dog Whisperer．

To find the right career, Millan encourages kids to do what they enjoy．"You can always find a job．But I find that happiness comes when you follow your passion．Success followed me because I was following my dream of being the best dog trainer in the world．"

Don’t you find that it is getting increasingly darker every day when you wake up for school? As winter comes, days become shorter while the nights become longer, in the past people slept more in winter, but in modern times we just use more electric light instead of sunlight to continue our normal routines.

But scientific research is finding that manhandling of electric light is making us sick.

Electric light is fooling the body’s biological clock into releasing awaking hormones ( 荷尔蒙)at the wrong times ,scientists say .This might be leading to seasonal fatigue (疲乏)and depression .

Much more than mental health is at stake, recent scientific studies have found that women, who work at night, have higher chances of getting breast-cancer.

“Electric lights are wonderful ,but as with a lot of other things ,we really mess ,things up ”said David Avery ,a psychiatrist (精神病专家).” Our ancestors evolved in a very regular light –dark cycle ,and our bodies just work better that way .”

Researchers have known for a long time that all living things have a biological clock that is linked to light ,Being of the natural day-night cycle can cause fatigue ,mood change and depression ,This is known as seasonal affective disorder ,or SAD.

Scientists disagree on the cause of SAD, Some say it is caused by winter’s late sunrises, others blame the early sunsets.

However, they all agree the perfect solution to SAD is to give up artificial light; it will quickly bring someone into a cycle of long, restful nights and easy awakenings at dawn.

But realistically most people need to use electric light in their everyday life. Ironically the next best solution is to use more bright lights to reset the body’s biological clock.

By getting bright light first thing in the morning it simulates (模拟)an earlier dawn and shifts the body clock forward ,according to Alfred Lewy ,a psychiatrist at Oregon Health & Science University .

A 2005 study done by the American Psychiatric Association showed that daily exposure to bright light was about as effective as medicine used to treat several forms of depression .
