Everyone wants to have a healthy heart. Still, heart diseases affect more than 1 in 3 adults in the United States. The good news is that some simple, everyday habits can make a big difference in your ability to live a healthy lifestyle. Here are some worst habits for your heart, and how to avoid them.
Watching TV
Sitting for hours on end increases your risk of heart attack and stroke(中风),“some exercise doesn’t make up for the time you sit,”says Harmony R. Reynolds, Why? The lack of movement may affect blood levels of fats and sugars. Dr. Reynolds advises walking around regularly and, if you’re at work, standing up to talk on the phone.
Leaving hostility and depression unchecked
Are you feeling stressed or sad? It can do harm to your heart. While everyone feels this way some of the time, how you handle these emotions can affect your heart health.“Those with stress are in greater danger; research has shown a benefit to laughter and social support,” Dr. Reynolds says. “And it’s helpful to be able to go to someone and talk about your problems.”
Cutting off from the world
It's no secret that on some days, other human beings can seem annoying and too difficult to get along with.
However, it makes sense to strengthen your connections to the ones you actually like. People with stronger connections to family, friends, and society in general tend to live longer, healthier lives.
Everyone needs alone time, but you should still reach out to others and keep in touch whenever you can.

Different people like doing different things；different people have different hobbies. My brother is fond of collecting stamps. He has a very good collection and he is proud of it.

On May 23,1989, Stefania Follini came out from a cave at Carlsbad , New Mexico．She hadn’t seen the sun for eighteen and a half weeks ．Stefania was in a research program, and the scientists in the program were studying body rhythms （节奏）。In this experiment Stefania had spent 130 days in a cave ,30 feet in depth．
During her time in the cave, Stefania had been completely alone except for two white mice．Her living place had been very comfortable ,but there had been nothing to feel her the time ．She’d had no clock or watches , no television or radio．There had been no natural light and the temperature had always been kept at 21℃
The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24hour day, she had stayed awake for 20～25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 171 bs in weight as a result!She had also become rather depressed (抑郁).
How had she spent her time in the cave?As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes.
The experiment showed that our body clocks are affected by light and temperature. For example, the pattern of day and night makes us wake up and go to sleep. However, people are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10:00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!Stefania stayed in the cave for a long time because___________．
| A．she was asked to do research on mice |

| C．she was the subject of a study |
| D．she needed to record her life |
