Lead is such a well-known health - perhaps even contributing to the fall of the Roman Empire- that it came as a shock to discover that toys played by children could contain lead. Doctors are now dealing with the aftershocks. Just how dangerous is this exposure? That's the question physicians are being asked by parents who find a lead-polluted Elmo, of Dora. Millions of others toys, lunch boxes and pieces of jewelry manufactured in China have been recalled because they contain lead either in the paint that coats them or as a component of the plastic used to make the item more flexible. The lead content in some of the toys recalled this summer was 180 times the amount allowed by law. Some pieces of jewelry were almost 100% lead. Experts advise that the items do cause a risk and that doctors should urge parents to check the comprehensive lists of recalled products on the Consumer Product Safety Commission's Web site and return any appearing on those lists to the manufacturers. If exposure is suspected, a blood test is in order . Since there is no safe level of this universal   element, the risk face by children for lead poisoning and its accompanying threat of learning disabilities and behavior problems is considerable. Doctors who have toys in their waiting rooms also are advised to see if any of them have been recalled and to check for chipped, flaking paint-even on those that haven't yet been recalled--since new announcements of toy risk continue. Question: Why does the author mention "the fall of the Roman Empire"? - To tell us a strange story. - To warn us to keep away from lead. - To explain why the Roman Empire fell. - To show how terrible lead poisoning is.

One day she felt so lonely that she wanted to reach out to someone. So she put pen to paper and started writing letters--letters to complete strangers. But these weren't sad letters about how she was feeling. They were happy letters, all about the other person, not her. She would write messages for people to have a "bright day" and tell strangers how outstanding they were, even if they thought no one else had noticed. Brencher began dropping the notes all over New York, in cafes, in library books, in parks and on the subway. It made her feel better, knowing that she might be making somebody's day through just a few short, sweet words. It gave her something to focus on. And so, the website The World Needs More Love Letters was born. The World Needs More Love Letters is all about writing letters--not emails, but proper, handwritten letters. Not traditional love letters, written to a real beloved, but surprise letters for strangers. They don't necessarily say "I love you", but they are full of kindness--telling people they are remarkable and special and all-around amazing. Brencher's initiative   has now exploded. She has personally written hundreds of letters. Last year, she did a TED talk, in which she talks about a woman whose husband, a soldier, comes back home from Afghanistan and they struggle to reconnect: "So she leaves love letters all over the house as a way to say: 'Come back to me. Find me when you can.'" And then comes another story of a man threatening to kill himself on his Facebook page, only to now be in the land of the living, with many love letters under his pillow. The World Needs More Love Letters Project works on the idea that _ ". It's about sharing positive energy, restoring confidence and happiness. There are now more than 10,000 people from all over the world joining in to write letters to the lonely and depressed, to basically tell them that everything will be okay.

The rest nearly fell out of their chairs laughing. "Don't be silly, only geniuses can become writers," the English teacher said, "And you are getting a D this semester." I was so humiliated  that I burst into tears. That night I wrote a short sad poem about broken dreams and mailed it to the Capri's Weekly newspaper. To my astonishment, they published it and sent me two dollars. I was a published and paid writer. I showed it to my teacher and fellow students. They laughed. "Just plain dumb luck," the teacher said. I tasted success. I'd sold the first thing I'd ever written. That was more than any of them had done and if it was just dumb luck, that was fine with me. During the next two years I sold dozens of poems, letters, jokes and recipes. By the time I graduated from high school, with a C minus average, I had scrapbooks filled with my published work. I never mentioned my writing to my teachers, friends or my family again. They were dream killers and if people must choose between their friends and their dreams, they must always choose their dreams. I had four children at the time, and the oldest was only four. While the children slept, I typed on my ancient typewriter. I wrote what I felt. It took nine months, just like a baby. A month later Crying Wind, the title of my book, became a best seller, was translated into fifteen languages and Braille and sold worldwide. I appeared on TV talk shows. I traveled from New York to California and Canada on promotional tours. My first book also became required reading in native American schools in Canada. People ask what college I attended, what degrees I had and what qualifications I have to be a writer. The answer is: "None." I just write. I'm not a genius. I'm not gifted and I don't write right. To all those who dream of writing, I'm shouting at you: "Yes, you can. Yes, you can. Don't listen to them." I don't write right but I've...
