The Healthy Habits Survey (调查) shows that only about one third of American seniors 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 batteryoperated 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 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：Be aware of germs. 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.
