1 . Today’s grandparents are joining their grandchildren on social media, but the different generations’ online habits couldn’t be more different. In the UK the over-55 s are joining Facebook in increasing numbers, meaning that they will soon be the site’s second biggest user group, with 3.5 million users aged 55-64 and 2.9 million over-65s.

Sheila, aged 59, says, “I joined to see what my grandchildren are doing, as my daughter posts videos and photos of them. It’s a much better way to see what they’re doing than waiting for letters and photos in the post. That’s how we did it when I was a child, but I think I’m lucky I get to see so much more of their lives than my grandparents did.”

Interestingly, Sheila’s grandchildren are less likely to use Facebook themselves. Children under 17 in the UK are leaving the site - only 2.2 million users are under 17 -but they’re not going far from their smartphones. Chloe, aged 15, even sleeps with her phone. “It’s my alarm clock so I have to,’ she says. “I look at it before I go to sleep and as soon as I wake up.”

Unlike her grandmother’s generation, Chloe’s age group is spending so much time on their phones at home that they are missing out on spending time with their friends in real life. Sheila, on the other hand, has made contact with old friends from school she hasn’t heard from in forty years. ”We use Facebook to arrange to meet all over the country,” she says. “It’s changed my social life completely.”

Parents have an important role to play if they want their kids to spend more time in real life. Peter, 38, who spends most of his time in front of a screen, is recently determined to set a better example to his kids. In the evening or at weekends, he would leave his smartphone home and take his kids out to nature.

5 . We all need to eat, and when we go to buy food at the supermarket, we’re offered many choice. But we often buy food that’s been produced in huge amounts and that’s traveled many miles before it ends up on our plate. So for some, growing their own food is a better choice – and it tastes good too!

From growing vegetables in little pots on your balcony to taking care of a small plot of land, there are many ways to produce home-grown food. It can be backbreaking work digging, weeding and watering the soil, but the result is fresh, home-grown fruits and vegetables, helping us keep a ‘five-a-day’ diet.

The recent Covid-19 pandemic lock-down means demand for homegrown food has seen a comeback in the UK. Miriam Dobson from the University of Sheffield, told the BBC that some people have been spending a lot of their time on their plots, growing plenty of fresh fruit and vegetables – which, at times, have been challenging to buy in supermarkets. She says “Coronavirus has reminded people of the weakness within our global food system. In such a difficult time, interest in self-support rises.”

But for those with limited space, a solution to grow your own vegetables lies closer to home – using pots. Sheila Brand lives in a third-floor flat in Rotterdam. She has managed to grow tomatoes and eggplants and is already harvesting raspberries. She told the BBC watching the plants grow “is very exciting: 'Oh it's got a new leaf!' ”

As well as the benefits of saving money and enjoying tasty food, growing your own from a balcony or window ledge not only improves your well-being and immediate environment, you can actually grow a lot of vegetables. So, maybe it’s time for us all to get planting and develop our green fingers!

6 . The Internet has become part of modern life, bringing convenient services to everyone who can connect. While it seems hard to live without the Internet, it also brings new problems. For example, individuals, organizations and even governments can become targets of cyber attacks.

The past week marked China's sixth annual Cybersecurity Week, held from Sept 16 to 22 nationwide. The opening ceremony and major activities were held in Tianjin. First launched in 2014, the event was designed to raise public awareness of the importance of fighting online threats and cyber attacks. The theme of this year's event is "cybersecurity for the people and by the people".

The leaking (泄露）of personal information now stands out. " Efforts should be made to raise people's sense of fulfillment, happiness and security in cyberspace," said President Xi Jinping in an instruction for the event. "The country will safeguard the security of personal information and citizens' legal rights and interests in cyberspace. According to a report from the 2017 China Internet Security Conference, more than 90 percent of Android smartphones for sale in China contained serious safety bugs. Such flaws (缺陷)allow hackers to control entire phones and obtain the users' passwords, bank information and more.

To protect personal information, China issued its first cybersecurity law in June 2017. One key part of this law is meant to protect personal information. It rules that network operators are not allowed to leak, change or damage the personal information they gather. They are also not allowed to give personal information to others freely.

Apart from China, issuing laws to protect personal information and prevent junk electronic information is a common practice in other countries.

7 . With people wearing face masks to protect themselves from being infected with the novel coronavirus, a concern now is how they are dealing with their used masks. As used face masks may carry the coronavirus, they shouldn't be carelessly thrown away as waste. Since the virus can survive for one or two days in wet conditions, the used masks may become a new source of infection.

Given that the garbage sorting has recently been carried out in only a few cities, mixed waste commonly exists. The mixture of polluted masks and recyclable waste may cause a possible danger to rubbish collectors when they put hands in the garbage cans to collect recyclable items. What's worse, if someone just throws a used mask on the street, someone might pick it up, or try to collect it to sell second-hand.

With the spread of the novel coronavirus, there has obviously been a high demand for protective equipment such as face masks among ordinary people, with the resulting generation of a huge quantity of what may be considered medical waste. Thus, the problem is how to deal with this mass of medical waste, particularly the used face masks outside of hospitals. Communities should have special trash cans around to collect used masks. If these are not provided, people should put the waste into plastic bags before casting them aside, so they are not exposed to the air.

As the main risk of medical waste is infectivity, disinfection, whether by steam, chemicals or microwave, is very important. According to regulations, only licensed companies should collect, transport and do the final management of medical waste. For example, medical waste must be collected in special containers,and be transported in special vehicles by qualified people.

8 . “Farm to table” is the name of a movement that encourages people to eat locally grown food. The farm­to­table idea has become more popular in recent years. But there is also a movement that brings “table to farm”. Its purpose is to connect people to the land and to honor local farmers by creating a sort of restaurant without walls.

Its founder, Jim Denevan, got the idea for this kind of “culinary adventure (美食探险)”, as he called it, ten years ago. He recently prepared tables for more than a hundred people at Briars Farm in Virginia. He and his eight­member team arrived the night before. Chefs (厨师) from a local restaurant prepared the dinner.

Jim Denevan’s brother is a farmer and he himself is a chef. He thought that the idea of a meal served right on the farm made sense, though not everyone agreed.

“But I wanted to make the idea work, so I decided to cross the country,” said Denevan. “I went all the way across the United States and set the table on farms, ranches (大牧场) and beaches, and all the places where food came from.”

“This kind of event connects us with a lot of enthusiastic people, people that we can form relationships with,” said Matt Szechenyi, who operates Briars Farm.

The tour of the farm ends at the dinner table. The meats in the meal come from Matt Szechenyi’s farm. The vegetables come from nearby farms. Guests and local farmers sit together.

Annoica Ingram came with a friend. “The food is wonderful. I appreciate their hard work. I see everything they have to do to take care of the animals and make sure they are well­cared­for. Without them, I think, we’ll have big problems,” she said.

9 . Smart phones are greatly changing the way we walk down the street. Office workers and young people are walking like the old as they check emails and messages.

Scientists have found mobile phones make us walk more slowly, with modest steps, to avoid falling over. The leader of the study said the walk is just like someone in their eighties. Researchers found people writing a text message walk more than twice as slowly as those without a phone, finding it harder to stay in a straight line.

The scientists examined 252 people walking while reading a text message, writing one, speaking on their phones or without their phones at all. Writing a text is the hardest activity, causing people to look down at their phone 46 percent more, and 45 percent longer, than when reading a message. This led people to walk 118 per cent more slowly than when they were without their phones. People walked almost a third more slowly while reading a text and 19 per cent while talking on the phone.

Smart phones were found to stop people from walking in a straight line, putting them at greater risk of running into other people, cars or street lamps. This increased the need to slow down and take more careful steps.

John Timmis said the idea for this study came from following someone walking down the street in the afternoon, who was walking as if he had had several drinks. I thought it was a bit early for that, then walked up alongside him and saw that he was on his phone. Simply being on the phone changes the way people walk.

10 . I am a strong believer that if a child is raised with praise, he will learn to love himself and will be successful in his own way.

Several weeks ago, I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines. I kept asking him to sit down, telling him that he would concentrate better. He sat but seconds later, as if he didn’t even notice he was doing it, he got up again. I was getting frustrated, but then it hit me. I started noticing his answers were much quicker and accurate (准确的) when he stood up. Could he be more intent (专心的) while standing up?

This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet, calm child was a sure way to success. This child would have the discipline (纪律) to study hard, get good grades and become someone important in life.

Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality traits (特点) and all you can do is loving and accepting them. As parents, throughout their growing years and beyond that, we need to be our kids’ best cheerleaders, guiding them and helping them find their way.

I have stopped asking my son to sit down and concentrate. Obviously, he is concentrating just in his own way and not mine. We need to learn to accept our kids’ ways of doing things. Some way may have worked for me but doesn’t mean we need to carry it through generations. There is nothing sweeter than being individual (个人的) and unique (独一无二的). It makes us free and happy and that’s just the way I want my kids to live their own life.
