[Q]: Article: Some people say that the best way to reduce the size of your waist is to do stomach exercise. Many people believe that when specific muscles are exercised, the fatty tissues   in the immediate area are burned up. The truth is that exercise burns fat from all over the body and not from one specific area. Of course, if you reduce the fat throughout your body, you will certainly see results around your waist too. Some people believe that you need to exercise twice a week in order to keep a sufficient level of physical fitness. However, studies directed by American scientists show that unexercised muscles lose their strength very quickly. Within 48 to 72 hours, you must use the muscles again to reestablish   the good physical effects. And what does that mean to you? American scientists concluded that while daily exercise is most helpful, exercising every other day or three days a week will keep a sufficient level of physical fitness. Is it true that you burn more calories running one mile than walking the same distance? The answer is no. The truth is that you use the same amount of energy whether you walk or run the mile, since in both cases you are moving the same weight the same distance. The speed does not matter. Of course, if you run rather than walk for 30 minutes, you will cover more distance, and therefore burn more calories. If your breathing doesn't return to normal within 5 minutes after you finish exercising, you have exercised too much. Five minutes or so after exercising, your breathing should be normal, your heart shouldn't be beating loudly, and you shouldn't be tired. 
 Answer: run fast for 30 minutes
[A]: If you want to reduce the fat around your waist, you should   _  .


[Q]: Article: Brownie and Spotty were neighbor dogs who met every day to play together. Like pairs of dogs you can find in any neighborhood, these two loved each other and played together so often that they had worn a path through the grass of the field between their houses. One evening, Brownie's family noticed that Brownie hadn't returned home. They went looking for him with no success. Brownie didn't show up the next day, and, although they made their efforts to find him, by the next week he was still missing, Curiously, Spotty showed up at Brownie's house alone, barking and jumping. Busy with their own lives, they paid no attention to the nervous little neighbor dog. Finally, one morning Spotty refused to take "no" for an answer. Ted, Brownie's owner, was continuously disturbed by the angry, determined little dog. Spotty followed Ted about, barking all the time, then rushing toward a nearby empty lot and back, as if to say, "Follow me! It's urgent!" Eventually, Ted followed Spotty across the empty lot as Spotty stopped to race back and barked encouragingly. The little dog led the man to a deserted spot a half mile from the house. There Ted found his beloved Brownie alive, one of his legs crushed in a steel trap  . Frightened, Ted now wished he had taken Spotty's earlier appeals seriously. Then Ted noticed something. Spotty had done something else besides leading Brownie's human owner to his trapped friend. In a circle around the injured dog, Ted found some food remains of every meal. Brownie had been fed that week! Spotty had been visiting Brownie regularly, in the hope of keeping his friend alive. Spotty had actually stayed with Brownie to protect him from hunger and other dangers, and keep his spirits up. Brownie's leg was carefully treated and he soon got well again. For many years thereafter the two families watched the faithful friends chasing each other down that well-worn path between their houses.
