The Healthy Habits Survey shows that only about one third of American seniors(年长者) have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
·Finding：A full 33% of seniors brush their teeth only once a day.
·Step： Remove the 300 types of bacteria(细菌) in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2. How many times did you wash your hands or bathe yesterday?
·Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their
hands only 4 times a day---half of the number which doctors recommend.
·Step：We touch our faces around 3,000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
·Finding：Seniors are not fighting germs as well as they should.
·Step：  Do you know it is not your toilet but your kitchen sponge（海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.
【小题1】What is found out American seniors?

What if there is a fire in your house? Would you know what to do? Here are several suggestions which might help you escape (逃生) from the fire.

Leaving the house through a door should be your first choice as an escape route. Windows on a higher floor may be a safe escape route if you could get help from another person.

     If you can see smoke in the house, stay low to the ground as you go to the door. In a fire, smoke and poisonous air hurt more people. You’ll breathe less smoke if you stay close to the ground.

If fire or smoke is blocking (阻塞) an escape route, you do this, firefighters (消防队员) will have difficulty finding you. The sooner they find you, the sooner you can get out.

Meanwhile, keep heat and smoke from getting through the door by blocking the cracks (缝隙) around the door with blankets, or clothing. If there is a window, open it all the way and stand in front of it. If you can get a piece of clothing, cover your mouth to keep from breathing in the smoke. This works even better if you wet the cloth first.

If your clothed catch fire during a fire, don’t run! You had better stop, drop to the ground, and roll. This will cut off the air and put out the fire.
