You can easily find that your sister or brother is different from you. You live together in the same house and have the same parents, but you have different personalities(性格).
Why? One possible reason is the way your parents treat you.
Firstborn children receive all the attention from their parents. Generally speaking, a firstborn has twice as many photos as any other child has. Parents usually give firstborns more responsibilities (責任)and depend on them to take care of younger brothers and sisters. As a result, firstborns are often responsible, hard-working, and serious. They often want to do well at school and in work. More firstborns became American Presidents, for example George W.Bush, George Washington and Lyndon Baines Johnson, than second or last-borns.
When a second child arrives, parents are more relaxed. The second child has to compete (競爭)with the first-born for parents’ attention and love. These children often choose different sports and hobbies to develop different personalities. They are often outgoing, but can be jealous and get angry easily.
The youngest child is usually the happiest, and has fewer responsibilities and more freedom(自由的). These children do well at school and in work, but have to be creative（創造性的） to get their family’s attention. They are often friendly and cool. Many famous talk-show hosts were born last.

Try this: for a whole day, forget about the clock. Eat when you’re hungry and sleep when you’re tired. What do you think will happen?
You may be surprised to find that your day is much like most other days. You’ll probably get hungry when you normally eat and tired when you normally sleep. Even though you don’t know what time it is, your body does.
Inside our bodies are several clocklike systems that follow a 24- hour cycle. Everyone is unique, which is why you might like to stay up late while your sister always wants to go to bed early.
Regularly staying up late can make kids do worse on tests and quizzes. And working shifts at night leads to higher rates of heart disease.
“There is a growing sense that when we eat and when we sleep are important parts of how healthy we are,” says Steven Shea, Director of the Sleep Disorders Research Program at Brigham and Women’s Hospital in Boston.
“During the night, we are prepared to sleep,” Shea says. “During the day, we are prepared to eat and move around, If you reverse ( 顛倒) what you are doing, everything is out of phase. That can have adverse consequences.
