Healthy Behavior Can Spread Like Illness
By Christopher Intagliata
If your friends arehappy—turns out you're more likely to behappytoo. If your friends areoverweight, that tooups[v.]the odds you'llpack on pounds[1]. Those effects have been shown in studies. And now researchers have identified another seeminglycontagious[2]quality:exercise.
[1]pack on the pounds: (idiomatic) To gain weight, especially as a result of vigorous or excessive eating. 增加体重；变肥；长胖
[2]contagious[kən'teɪdʒəs]
1）A contagious feeling spreads quickly among people. （情感）具有感染力的，蔓延的
Fear iscontagious.
恐惧是会传染的。
2）A contagious disease can be caught by touching someone who has the disease or a piece of infected clothing. （疾病）接触性传染的
The infection is highlycontagious, so don't let anyone else use your towel.
这种传染病极易传染，所以不要让别人用你的毛巾。
3）A contagious person has a contagious disease. （人）患传染病的，带传染源的
Keep him out of school until he's notcontagiousanymore.
在他不再传染前，别让他上学了。
The investigators analyzedthe running activityof more than a million individuals worldwide who used anexercise tracking devicefor five years. And they usedweather patternsas a way to randomly examine different parts of that global network.
"If it happens to be a really nice day out, sunny and not too hot, not too cool, that willinduce[诱使;引起;导致]people to run more.”Sinan Aral,a computational social scientistat MIT. “If it's a rainy day and cold, that willinducepeople to stay in more on average."
And since cities have different weather patterns, he says, this natural experiment allowed them to ask:Does a rainy day in New York affect running in San Diego?"If the weather in New York causes changes in the running behavior in San Diego, it can really only be happeningthru[同through]peer influences[同龄人影响]of the friends who live between New York and San Diego."
And that is exactly what he and his colleague saw: thatthe behavior of one city's runners could indeed affect the behavior of runners in another socially connected city. The study is in the journalNature Communications. [Sinan Aral & Christos Nicolaides, Exercise contagion in a global social network]
A fewcaveats[3]:womentended to be influenced more by thefemalerunners in their networks. Andless active runnerstended to influence more active runners to run more, but not so much the other way around. Still, this could bevaluableintel[4]for health professionals.

[4]intel:secret information about the governments of other countries, especially enemy countries (a short form of the word "intelligence")
What was the point of getting a man onto the base if it wasn't to gather intel?
"We have to start thinking about consumers and citizens as networked consumers and networked citizens. Where they are influenced by and influence their social network in very strong and dynamic ways, that will change the way a particular intervention succeeds or fails."
In other words - if yourprescription[5]is more exercise? The doctors might want to write a prescription for your friends and family, too.
