Secondhand smoke isn’t just a health threat to people.It can also hurt dogs and cats,veterinarians say.
According to the Centers for Disease Control and Prevention,more than 126 million Americans who don't smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places.This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency.
“Making the leap from the effects of secondhand smoke on humans to their effects on pets isn't a big one,” says veterinarian (兽医专家) Carolynn MacAllister of Oklahoma State University.
“There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets,” MacAllister said.“Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds.”
Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate.Dogs affected with nasal cancer normally don't survive for more than one year.
“Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren't as effective at accumulating the inhaled secondhand smoke carcinogens,” MacAllister said.“This results in more carcinogens (致癌物质) reaching the lungs.”
Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant.
To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said.

1. __________
Lin(Jeremy Shu-How Lin)got to start for the Knicks because they had to start him. They had too many injuries. Baron Davis was gone. The other point guards were out. Carmelo Anthony was injured. Amare Stoudemire had to leave the team because of a family death. Lin could have squandered the opportunity and we would have never have noticed. But he made the most of it. You never know when opportunities are going to arise in life. Often, they’re when you least expect them. Make the most of them. Don’t waster them.
2. __________
Lin isn’t Michael Jordan or Kobe Bryant. He’s not a pure scorer. He’s a passer and distributor – who can also score very well. It didn’t work for him in Golden State or Houston – where he was before landing at the Knicks. But Mike D’Antoni’s system at the Knicks has been perfect for him to show off his strengths. You’ve got to do your best to understand what your strengths are and then ensure that you’re in a system (a job or organization or industry) that is a good fit for those strengths. Otherwise, people overlook the talents you bring to the table.
3. __________
You probably manage people at your own company today. Are you sure you don’t have a Jeremy Lin living among you now? How do you know that “Mike” couldn’t do amazing things if you gave him a new project to run with? How do you know “Sarah” isn’t the right person to take the open job in London that you’ve been talking over with your colleagues? We put people around us in boxes. He’s from Harvard. He’s Asian-American. Not sure he can play. How many assumptions have you made about talent around you? Don’t be like the General Managers in Golden State and Houston, and let talent slip through your fingers. With all their money, scouts(球探), and testing, they didn’t have a clue what they had in their hands. Do you know what your people (or even yourself) are really capable of? Take off the blinders of assumptions you wear when you look at the world.
4. __________
If you one day are lucky enough to have newspapers want to put you on the cover in order to sell more, don’t let it get to your head. It’s been remarkable watching how humble Lin remains through all this media craze. It makes his teammates and fans love him that much more.
5. __________
Lin couldn’t have seized his opportunity if he hadn’t worked like crazy for years perfecting his skills. There are no short cuts to hard work. Success is a by product of that. If you’ve got a Tiger Mom who’s always pushed you to work hard, great. If not, let your conscience be your own Tiger Mom! Get up early, stay up late. Nobody gave Lin any free passes. Why should you get any? You can only control what you control and that means you’ve got to work harder than anyone else you know.
