How do you feel after you've stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes.
Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown.
In a similar way, new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.
The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of period3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers.
Results showed that the people with the short form of period3 performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating.
After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off.
People with the long period3 gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form.

Love, success, happiness, family and freedom----how important are these values to you? Here is one interview which explores the fundamental questions in life.
Question: Could you introduce yourself first?
Answer: My name is Misbah, 27 years old. I was born in a war-torn area. Right now I’m a web designer.
Q: What are your great memories?
A: My parents used to take us to hunt birds, climb trees, and play in the fields. For me it was like a holiday because we were going to have fun all day long. Those are my great memories.
Q: Does your childhood mean a lot to you?
A: Yes. As life was very hard, I used to work to help bring money in for the family. I spent my childhood working, with responsibilities beyond my age. However, it taught me to deal with problems all alone. I learnt to be independent.
Q: What changes would you like to make in your life?
A: If I could change something in my life, I’d change it so that my childhood could have taken place in another area. I would have loved to live with my family in freedom. Who cares whether we have much money, or whether we have a beautiful house? It doesn’t matter as long as I can live with my family and we are safe.
Q: How do you get along with your parents?
A: My parents supported me until I came of age. I want to give back what I’ve got. That’s our way. But I am working in another city. My only contact with my parents now is through the phone, but I hate using it. It filters(過濾) out your emotion and leaves your voice only. My deepest feelings should be passed through sight, hearing and touch.
1.In Misbah’s childhood, .
A. he was free from worry
