Bad behavior is something that most people don’t want to tolerate. However, we have had to tolerate it more and more with each passing year. There seems to be no concern for other people’s feelings; nor do we seem to care about other people’s property. We live in an age where saying what is on our minds has priority over any harm that it might do.

There are ways to deal with bad behavior in modern times, though. Too many of us let bad behavior go because we don’t want to rock the boat. This is the time that you should rock the boat and rock it hard. Let people know that you expect it to change. That is the key to dealing with bad behavior. If it continues, take the proper action for the situation you are in. If you have developed the habit of bad behavior, take a hard look at it and then change it. You can’t expect others to behave well if you aren’t willing to look at your own bad behavior and change it.

If you don’t have control over anything in a situation, just walk away from it and move on to something that you do have control over. You needn’t feel ashamed of that. Besides, you must stand firm in what you believe. You can’t control what other people do, but you can control what you do about it. You can’t go wrong if you stand firm in what you believe. Understanding your responsibility is also important. Don’t try to take on the responsibility for other people’s behavior. Take care of what you have to and do it in the way you know it should be done. The rest will take care of itself.

Bad behavior is on the rise with more and more people behaving badly without having to pay any consequences. Worry about how you behave rather than how others behave. Pretty soon, it just may catch on.

Bad teeth can be painful — and worse. They can even be deadly. Infections (感染）of the gums (牙龈）and the teeth can cause bacteria (细菌）to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk. For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿 保健）he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物）to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (法琅质)， the hard surface on teeth, to help prevent holes from forming.
