We had no idea that he had health problems, and we woke up early one morning to the cat crying out painfully. We immediately rushed him to the vet's where the vet said that at best treatment might lengthen his life by two to three months. We did not want to see him suffer, so we chose to kill the cat in a painless way. I am having a rough time! I cry when I am alone. I cry when I see pet commercials on television. I put away everything that reminds me of the cat. But the last sight of seeing the cat in pain plays over and over in my head. My kids seem alright with what has happened, but why am I struggling? It has only been one week since his passing, so I hope things will get better. Do you have any suggestions? Yours, Sad DEAR SAD: There is no loss quite like the loss of a pet; these animals keep us company through important life passages and are beloved witnesses to our human lives. I understand your instinct to put away all of your cat's things, but it may help you now to memorialize your pet by using these things. Each family member can write down favorite things about him or memories of him; read their memories aloud and put the papers inside his bowl. The idea is to replace those painful last memories with much more lively memories taking place over the most of the animal's life. Time will then do its job, which is to affect your feelings. And then, when you're ready, I hope you will adopt another animal and give it the opportunity to[:Z-X-X-K]share your life. Yours, Amy Question: The author cried when seeing pet commercials on television because  _  . - she was alone at home - she thought of her lovely cat - she didn't like to see the things of the cat - her children showed no feeling over the cat's death

If you cut down on the time you spend sitting, you might live longer. New research shows that sitting less than three hours a day might extend your life by two years. Just the opposite, says Peter Katzmarzyk. He is a scientist at the University of Louisiana in the southern United States. He says that sitting is _ in our lives. "We sit while we're eating; we sit in the car; we sit while we watch TV. Many of us sit for many hours at work. " But, he adds, that does not make sitting good for us. The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. Exercise is important. So is not sitting. "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. Even if you exercise for 30 minutes a day, what goes on in the other 23-and-a-half hours a day is also very important." Mr. Katzmarzyk and his co-workers are part of a new generation of researchers studying how sitting all day affects length of life. This is a relatively new area of study--studies that have assessed the relationship between sitting and mortality  or television viewing and mortality. Making uses of the few studies available to them, they found that cutting television time to less than two hours a day could add one-point four years to life. New desk designs are helping Change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. That's one of the strategies that many companies are using now. Some companies may equip their employees with a "standing desk" or a "treadmill desk". Other companies may not buy one for everybody, but they'll have a bank of these desks where people can go for an hour a day and answer their emails or...
