4、Because osteoporosis (骨质疏松) often causes no symptoms at all until a fall breaks a bone, the only way to tell if you have it is through a bone mineral thickness test.This is advised for anyone over 50 who has suffered a broken bone and all women over 65.Right now, the test involves lying on your back while the arm of a special X-ray device moves over your body to measure the thickness of various bones.

CyberLogic, a New York R&D firm, has developed a simpler device that’s nine inches high, runs on four AA batteries and scans bones with ultrasound. If the portable machine proves as reliable as X-rays, it could be a breakthrough, says New York osteoporosis expert Dr. Ethel Siris.“A small device like this could make bone checkups part of a routine office visit, because it’s both affordable and user-friendly.” If testing shows that you have osteoporosis, some major advances in treatment can help.While there are several effective medications on the market, including Fosamax, Actonel, Evista, Miacalcin and Forteo, the latest wonder drug is Boniva, the first once-a-month pill for osteoporosis.The FDA recently approved this drug, which works by reducing activity in cells responsible for bone breakdown.

Should osteoporosis get severe enough to break a vertebra, doctors have a new way to make repairs: Two tiny balloons are inserted into the bone through surgical tubes.The balloons are expanded to push the bone back into its normal position, then bone cement is used to keep it from breaking again.

3、Be careful! Someone may use the truth to deceive.When he tells you something that is true, but leaves out important information that should be included, he can create a false impression.

For example, someone might say, “I just won a hundred dollars on the lottery.It was great.I took that dollar ticket back to the store and turned it in for one hundred dollars!”

This guy’s a winner, right? Maybe, maybe not.We then discover that he bought two hundred tickets, and only one was a winner. He’s really a big loser!

He didn’t say anything that was false, but he purposely left out important information.That’s called a half-truth.Half-truths are not technically lies, but they are just as dishonest.

Untrustworthy candidates in political campaigns often use this tactic.Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs.Then she seeks another term.One of her opponents runs an ad saying, “During Governor Smith’s term, the state lost one million jobs!” That’s true.However an honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.”

Advertisers will sometimes use half-truths.It’s against the law to make false claims so they try to mislead you with the truth.An ad might boast, “Nine out of ten doctors recommend Yucky Pills to cure nose pimples.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Corporation.

This kind of deception happens too often.It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
