In the home, we could try not to waste foods. Use a digital meal planner to get a right amount of food so that everything we buy and cook gets eaten. Learn how to store foods to keep them fresh longer. Be sure to use proper ways to keep our home warm. For example, we can replace old windows with energy-saving ones.

At the store, we could green our habits. Buy reusable plates, but not single-use ones. Buy home tissue not made of materials which may lead to destruction of forests. Buy glass cups instead of paper ones.

In the community, we could help keep its plants healthy. Take part in tree-planting projects or grass-cutting activities to help plants grow well.

【推荐1】Traveling is a very good activity. When you are fed up with your work and are allowed to take a holiday, you can go to the beautiful spots to enjoy the beauty of nature and the special character of other cities. You can breathe fresh air, visit some places of interest, meet different people and make friends with them. Then you will forget your tiredness and troubles and be more healthy. As a result, you will feel fully relaxed and you will have the energy to undertake the new tasks waiting for you.

But sometimes, traveling is not an enjoyable thing. For example, when the bus or car you take has a bad accident, you may be trapped in it and waste your time. What's more, the weather can be changeable. If you are climbing a mountain, it may rain suddenly. You may be caught in the rain and may catch a cold. The worst thing is that you may have your money stolen or that you may have an injury. All these are terrible things that can happen to a tourist.

Therefore, before going on a trip, you must prepare yourself carefully. Firstly, you must have clear information about the weather. Secondly, you should choose a good companion so that you can help each other. Thirdly, you must be careful everywhere and try to avoid accidents. If you do these, you can enjoy your travels better and reduce unnecessary troubles.

Writing in the journal BMJ Open, a Singapore-based team of researchers said regular physical activity “improves physical and mental health, and relieves the risks and effects of chronic(慢性的) diseases among older adults”.

The team randomly chose adults from the town of Yishun in Singapore, and asked them to complete cognitive function tests as well as activities to assess their physical capabilities, such as standing up from a chair as quickly as they could. Participants were also quizzed on their levels of physical activity, including the amount of light housework and heavy housework they did, and were assessed for their risk of having a fall based on measures such as knee extension strength. The study involved 249 participants aged 21-64 and 240 participants aged 65-90. Most of those who reported doing high levels of heavy or light housework were women.

After taking into account factors including age and sex, the team found cognitive scores and attention scores were 8% and 14% higher respectively for older adults doing high amounts of heavy housework—on average 131 minutes a week—compared with low levels, which appeared to amount to none at all. Sit-to-stand time was shorter for older adults reporting high amounts of heavy housework compared with low amounts, while they were also assessed as being at lower risk of having a fall.

Dr Shiou-Liang Wee, the co-author of the research, said health messaging on staying active should not just be about recreational physical activities. “Housework is a purposeful activity performed by many older adults. Independent of recreation, commuting (通勤) and other work-related physical activity, heavy housework is linked to sharper memory and better falls protection in older adults,” he said.
