“Old wives’ tales” are beliefs passed down from one generation to another. For example, most of us remember our parents’ telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time.

Did your mother ever tell you to eat carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration.Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic (蒜) is good for you, too. It can kill the type of virus that causes colds.

Unfortunately, not all of Mom’s advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems? Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars.

Even though science can tell us that some of our traditional beliefs don’t hold water, there is still a lot of truth in the old wives’ tales.After all, much of this knowledge has been accumulated (积累) from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false.

Personalized Exercise

As the start of every year, many of us promise ourselves that a certain number of times a week we will go to the gym or attend an exercise class. But finally many of us just struggle to fit exercise into our lives, or start off well and then give up. Why do we have a good plan at the beginning and fail to achieve it in the end? How can we deal with the problem? 【小题1】

It is important to determine your motivation first. Are you mainly interested in de-stressing or in getting fitter?

You could choose solitary exercise, such as walking the dog or doing some gardening. 【小题3】 There are quite a lot of them, such as walking and running groups, dance classes, etc. On your own, you could go horse riding or swimming, or just download fitness exercise programs and do it at home.

【小题4】 If you have free time at the weekend, you could book some time with a personal trainer, who can come to your house, or you could meet him at the gym. If your life is not as regular, you could choose the next couple of minutes you have to try an exercise DVD, or put your running shoes on and run for any length of time.

As you see, everything counts when you are doing exercise. Whatever your lifestyle is, you will be able to have something that suits you. 【小题5】Just sit down with a cup of tea, read this article again, and have a think about your options. Then finish the tea, get up, get going, and don’t stop.

Make your fitness goals known. Tell your family, friends and co-workers about your fitness goals and encourage them to ask you how your goals come along. 【小题1】

【小题3】 If you’re new to exercise, it’ll be better to have a fitness professional set your goals rather than doing it alone. That means setting the weights on machines for you, determining how long you should walk or run, or giving you a time limit for the running machines.

Fit people keep energetic during their entire day. 【小题4】 You can simply stand up and walk around whenever you get on the phone and always take the stairs, not the lift.

Do it for charity. 【小题5】 If you fall into that category, then find a way to use your charitable nature to motivate yourself to exercise. For example, donate & 1 for every mile you walk. Or commit to several fund-raising events that involve walking, biking, dancing, or a sports match.
