For more than six million American children, coming home after school means coming home to an empty house. Some deal with the situation by watching TV. Some may hide. But all of them have something in common. They spend part of each day alone. They are called latchkey children. They’re children who look after themselves while their parents work. And their bad condition has become a subject of concern.

Lynette Long was once the headmaster of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of kids had chains around their necks with keys attached. I was constantly telling them to put them inside shirts. There were so many keys, it never came to my mind what they meant.” Slowly, she learned they were house keys.

She and her husband began talking to the children who had them. They learned of the impact(影响) working couples and single parents were having on their children. Fear is the biggest problem faced by children at home alone. One in each three latchkey children the Longs talked to reported being scared. Many had nightmares and were worried about their own safety.

The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall, under a bed in a closet. The second is TV. They’ll often play it at high volume. It’s hard to get statistics on latchkey children, the Longs learned. Most parents are slow to admit they leave their children alone.

When it comes to the prevention of heart disease, women need to pay attention to their own special risks. And so do men. Surprisingly, even children and teens need to be aware- or at least the parents who want to keep them safe do. Thankfully, scientists have also made great leaps in figuring out the specific prevention strategies that work best for all. So now, knowledge is your best protection.

What Men Need to Know

According to the American Heart Association (AHA), at least half of the people who die suddenly from heart disease each year had no clue they were sick. Some think that half of all heart attacks strike out of the blue. Not true, insists Jennifer Mieres, a spokeswoman for the AHA. A 2004 study found that at least 90 percent of first heart attacks are caused by well-known problems like high cholesterol(胆固醇) or diabetes. “If you look closely,” says she, “you’ll almost always find a risk factor that was undiscovered, ignored, or not adequately treated.”

Lifestyle changes like adopting a healthy diet, getting out for regular exercise, avoiding tobacco, losing weight are the first line of defense.

What Women Need to Know

There are some special considerations for the women who are  healthy and want to make sure they stay that way. First, they shouldn't smoke-no one should, but the habit is even harder on women's heart than it is on men's.

Women who find that they are at risk should talk to their doctor about taking a statin(他汀,药物名). Indeed, statins reduce the risk of heart disease, but there has been not enough evidence that they help high-risk women and it can't guarantee the long-term safety. So it's worth noting that a healthy diet and exercise also reduce cholesterol.

What Parents Need to Know

Last year, a study showed that overweight children and teens have arteries(动脉)that look like those of an average 45-year-old. New guidelines say these children should get a cholesterol test by age ten -- and even urge doctors to consider statins for those most at risk if nothing else works. The recommendations caused oppositions. Lifestyle changes such as diet and exercise are the best strategy, says Dr. Greer, a professor at the University of Wisconsin School of Medicine. Statins should be considered only for kids in danger.

I always carry at least $3 in my car and also in my pocket. I save it for the person who asks if I can “spare some  36 ”. Smiling and making eye contact, I always   37 very cheerfully with a comment like, “Yes, I would love to”  38 “It would be my pleasure”. And I give them the  39  .
Then I  40 it with my next $3 for the next person. I   41 spend this money myself. I honor the idea that it belongs to the  42 of the next person who asks for it. Three dollars is a small  43 , yet it means a lot to the person who might only expect 25 cents,  44 when delivered with respect to them.
I have also formed the habit of carrying  45 I think the needy may be able to use. I carry hats, socks, gloves, and an umbrella. Recently I  46 some care packages for the homeless. It  47 to me that things like band-aids, toothpaste, aspirin, combs, as well as food would be of use. I imagined that they would need things that are not easy to  48 , so I chose plastic or paper containers. The folks who  49 them were delighted.
But I think it’s not just that I give them things that  50 . It’s that I see them for the beautiful ray of lights that they are. I know that they are  51 expressions of God and that this is how they are at the current time, not who they are. I am  52 to also give a hug and a smile with the money. And I always remember it is they who bless me with the  53 to be kind! What a joy! I felt  54 good and proud of what I had done. See, that’s the added  55 about completing acts of kindness —you feel fantastic.
