“Hello” is one of the first words we learn as babies, yet it’s one of the last ones we think to use as adults. That’s unlucky, because saying hello is more than just saying hello. How might the world change—how might we change—if we mastered this word? ①I spent one month saying hello to every person I met. Here’s what I’ve learned.
* It can make the students more active. In a study on this subject, Allan Smith, an assistant professor, had middle school teachers greet their students individually (个别的) each morning. And the whole day, the students behaved actively because of this exchange of greetings. School went from impersonal to personal and that caused more class participation (合作) and better grades.
* Environments influence friendliness. One study found that people in the city were less likely to shake hands with a stranger than those in the countryside. ②And researchers think pleasant environments can encourage more smiles and hellos. For example, people in vacation spots were much more friendly than those hurrying to work downtown.
* It improves people’s health. It’s impossible to say hello without smiling. And smiling has been shown to lower blood pressure, reduce stress and bring happiness. Obviously, a smile creates a similar effect in the recipient (接受者).
So maybe we can make the world a better place by saying hello. After a month of doing it, I feel lighter and more connected and I have a better sense of happiness.
