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：About 33% of seniors brush their teeth only once a day.
·Step：Remove the 300 kinds of bacteria 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 that doctors advise.
·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.

You may think that sailing is a difficult sport, but it is really not hard to learn it．You do not need to be strong．But you need to be quick．And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat．The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind．This means the wind and the boat are going in the same direction．Then you must always keep the sail outside the boat．It should be at a 90° angle (角度) to the boat．Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat．In this case, you must keep the sail half way outside the boat．It should be at a 45° angle to the boat．It needs to be out far enough to catch the wind, but it shouldn't flap (摆动)．It shouldn't look like a flag on a flagpole．If it is flapping, it is probably out too far, and the boat will slow down.
Sailing against the wind is not possible．If you try, the sail will flap and the boat will stop．You may want to go in that direction．It is possible, but you can't go in a straight line．You must go first in one direction and then in another．This is called tacking．When you are tacking, you must always keep the sail inside the boat.

In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five days off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I’d hitch a ride (搭便车).
I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn’t give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured (使……放心)me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.
Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favor I’d been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.
After a few moments of small talk, the man said to me, “You haven’t changed a bit, even your red hair is still the same.”
I couldn’t remember where I’d met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.
