【推荐2】A cycling training at Queen Mary homeless women's hostel (收容所）in London starts. Eleven women discuss what they're hoping to achieve in today's training. Then they push their bikes to a basketball court to practice in an off-road environment. Supported by instructor (指导员)，they practice riding by themselves. Sometimes these women feel a little tired because they take medicine,but they have all made up their mind for cycling training.

Last year Queen Mary approached Sustrans (a charity) to set up a cycling club for women.Many of them have low levels of fitness. All have survived challenging situations ranging from social isolation (孤立) to abusive(虐待的) relationships. The hostel staff,who are experienced mental health experts, try to develop cycling to build the women's confidence and give them access（进入权 ) to other fields of society. The hostel is moving away from traditional treatment of mental health with the belief that cycling could be a really useful tool in helping the women live on their own. After the success of a 10-week pilot project, the cycling club received financial support of £10, 000 to continue the club.

In modern society, homelessness and mental health problems often go hand in hand. Studies have shown that physical activities,including walking and cycling, can be used to overcome and even prevent stress,depression and anxiety. They can be more effective than medical treatments.

Women,however,are less likely than men to take part in physical activities. Women in the UK make nearly three times fewer cycling journeys than men. Two main causes of this are traditional barriers-mostly because women still undertake most household tasks- and fear of judgment. The network of bike paths has been expanded (扩展)   yet the “build it and they will come" approach ignores the fact that not all people start from the same point. Social interventions (干预) are a useful way to achieve equality of access to cycling.

By the time I wake up, the notifications have already started rolling in; as I’m going to bed, they’re still coming. In between, I try to keep up, but all it takes is one 30-minute meeting before I’ve somehow gotten 100 new messages. I scroll up and up, trying to find where I left off, like I’ve lost my place in a book that keeps getting longer.

For better or for worse, we might be in the Age of the Group Chat. One study found that less than 2 percent of participants had only one-on-one chats on social media. 42 percent said that group chats can feel like a part-time job. Other studies have found that group chats can contribute to group bond and shared fun. A group text can be like a reminder that you’re part of something. Some researchers call this “ambient virtual presence”: Even when you’re alone, you’re not alone. This is like bats and dolphins producing a continuous sound and use the resulting echo (回声) to sense what’s around them.

But taking in too many signals can create a “waterfall type of effect,” where messages keep flooding in and adding up. Eventually, you’re underwater. Adding to the disorder, without a standard rule, people have very different ideas about group norm and what degree of responsiveness is required—which can cause real tension.

Fear of that tension can make wordless or even leaving a chat feel dispiriting. And anyway, you might not want to miss out. The desire isn’t to exit the room so much as to break a window. If group messaging is like echolocation, then disconnecting means lost.

Ultimately, most of us do want connection, even if it involves some duties; we’ll take quantities of messages when we’re busy if it means we can reach out when we’re hurting. A general advice is to give up grexts that are carrying on but that don’t really interest you. But when you can’t, you’ll just have to accept that belonging takes some effort. That’s the nature of relationships, right?
