Dear Mr. Lim,

My name is Mary Taylor. I’m a 14-year-old girl. I want to be a pilot. I spend hours watching the planes take off from the airport. I love traveling to new places by plane and the idea of flying people around the world!

I’m not sure whether it’s the right job for me. I want to decide soon. I hope to start training early. I want to be young when I’m flying a Boeing 737 or even an A380.

I have so many questions about the job-do you get paid well? I want to make lots of money because I want to have a big family and a big house. Is it fun? Is it safer than being a doctor, a policewoman,etc.?Is it really hard? I’m a girl,so will I be discriminated against（被歧视）? If I decide to become a pilot, where and when should I start training?

My only brother also says if I want to be a pilot, I have to be really good at math, but I’m only OK at math.

Being a pilot looks like one of the coolest jobs in the world. Could you please write to me soon? Thanks so much, Mr. Lim!

Yours,

Mary Taylor

Keeping a busy social life among lots of friends may keep people thinner than spending several hours in a gym, according to scientists. Scientists believe social activities can release a brain chemical that changes white fat into brown fat. Brown fat burns calories (卡路里). To produce heat, while white fat keeps calories and make us fatter.

Changing white fat into brown fat is very difficult, generally requiring long-term exposure to cold conditions or making part of the body’s nervous (神经的) system active. However, scientists from Ohio State University think that having a busy social life is an even better way of carrying out this change.

Tests on mice showed that those lived in large communities and had more space and toys lost half of their stomach weight in four weeks, even if they ate more than those in boring, lonely environments. Researchers said that social excitement helps lose weight.

However, social activities make some people worried. Study writer Dr Matthew During said, “I’m still amazed at the degree of losing fat that happens. We often think of stress (压力) as a negative thing, but some kinds of stress can be good for your health.”

Explaining how new technology had reduced the chance for people to communicate face to face, he added, “It’s not just because of being short of exercise and high calorie foods, but an increasing lack of social activities. Loneliness is a deep cause of cancer and death, it’s just as dangerous as smoking. Social activities are very important.
