                                                                   We Are What We Do

     When was the last time you gave blood? Or donated money to charity(慈善机构) ? Or, in fact, did

anything; to benefit the world?

     And why, in this age of communication, are we still so isolated(孤立) from each other?

     More than 2 million elderly people are expected to be living alone, with no family, by the end of the

next ten years.

     It does not have to cost a fortune to make a real difference. The We Are What We Do organization

has launched a book-Change the World for a Fiver.

    Inside are 50 simple things you can do to help mankind. They include recycling books, using energy

saving light bulbs (灯炮)  and " reverse haggling" in charity shops-paying more than the asking price.

     They may seem small but they are by no means in significant(无意义的). Metro has joined forces

with We Are What We Do, a branch of the Community Links charity.

     From Monday we will be asking readers to complete an action each day and report how successful

and fulfilling it was.

     Community Links founder David Robinson said, "We are delighted to be working with Metro. With

around 2 million Metro readers, we hope that 2 million of you are inspired to act and will help to bring

this exciting vision(梦想) to life."

     The $ 5 book is on sale at Waterstones, WHSmith, Sainsbury's, Ottakers, Borders and online at

Amazon. Co. uk.
