Osteoporosis and Men

Mention the word osteoporosis in the manly world of testosterone(睾丸素)，professional basketball and the XFL(美国最新的职业足球联合会)，and you’re likely to get a wave of the hand and a dismissive(轻蔑的)“That’s a woman’s disease．”Not S0．More than 2 million American men have been found to have the thinning bones and skeletal(骨骼的)weakness of osteoporosis(骨质疏松症)，and an additional 3 million are at an increased risk of developing them．

It’s true that osteoporosis strikes women with much greater frequency than men-in some studies as much as four to six times as often．But that’s no reason to brush it off as“their’ disease．It's a mere stroke of gender luck that men’s bones tend to grow larger。stronger and denser．Also paying dividends are those spots that boys(and，increasingly，girls)play as children—running up and down basketball coups，soccer and baseball fields．As it happens．physical activity is one of the more important ways to increase bone density and protect bone health．

But even the most active men cannot ignore certain facts of life．All of US build up Our bones during the first three decades of life，typically reaching peak bone mass in the early 30s．Around the age of 35，we begin gradually to lose some of this bone mass．Women ultimately give up between 30％．Though mass loss in men is lower, it still makes US vulnerable to back pains and bone fractures．In fact，this year alone American men will suffer as many as half a million osteoporosis-related breaks，mostly in the spine，hip and wrist．These are not only painful；thousands die each year from fracture—related complications．

For many of US，however, there’s still time．Of all the side effects of aging，osteoporosis is one of the more preventable．through diet，exercise and changes in lifestyle．The two key nutritional substances for bone health are calcium(钙)。which makes bones stronger, and vitamin D，which helps the body absorb the calcium．

Exercising is also important。with emphasis on weight-bearing activities in which bones and muscles work against gravity．Lifting weights and working out on resistance machines can help preserve bone density．

Be careful about what’s in your medicine cabinet．Prolonged use of some medications，such as steroids(类固醇)，can weaken your bones．Smoking and drinking are both bad for bones。as is prolonged weightlessness，for anybody who plans to work on the space station．

Why Do People Shrink？

Did you ever see the movie Honey, I shrunk the kids？ It's about a wacky(古怪的)dad (who's also a scientist) who accidentally(偶然的) shrink's his kids with his homemade miniaturizing (使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size.

(46) It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can*t be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all？

(47) As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. (48) . But perhaps the most common reason why some older people shrink is because of osteoporosis (骨质疏松症).

Osteoporosis occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. (49) . Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people—especially women, who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit.

Did you know that every day you do a shrinking act？ You aren't as tall at the end of the day as you are at the beginning. (50) . Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again.

A. They end up pressing closer together, which makes a person lose a little height and become shorter.

B. That's because as the day goes on, water in the disks of the spine gets compressed (squeezed) due to gravity, making you just a tiny bit shorter.

C. Over time, bone is said to be lost because it's not being replaced.

D. Luckily, there are things that people can do to prevent shrinking.

E. For older people, shrinking isn't that dramatic or sudden at all.

F. There are a few reasons.

A.osteotomy

B.osteopathy
