Body language affects your interactions with other people and yourself.Many people don't realize just how powerful body language is when it comes to self-esteem and self-confidence.Maybe your mother told you to smile, even if you don't feel like it,because it can help you and the people around you feel better.This old piece of advice has real roots in reality, because your own body language has a powerful effect on you and the people around you. Smile for a few seconds and notice how you feel.You might feel a bit silly,but chances are you also feel a more positive feeling.Psychologists often use this technique to help people with depression lift their spirits, encouraging them to try to smile as much as possible.The way your body moves also affects your self-esteem and self-confidence.Stand up and walk across the room with your shoulders forward,your head down,and your feet moving heavily.How does it feel? Now walk back across the room with your shoulders square and back,your head held up,and your feet moving lightly.What differences do you notice?So,your own body language does have an impact on your daily life. One advantage to knowing this is that it gives you a greater amount of control over your own feelings and attitude.Of course a smile alone is not going to correct a great deal of sadness, or fear,but when used regularly and in combination with other non-verbal expressions, it can help you start to feel better.Another part of applying body language to your daily life is your appearance.What happens when you just throw on a pair of jeans and an old T-shirt? How do you feel? Now think about when you get dressed up in nice clothes with your hair neat and makeup looking good?How do you feel? Chances are the simple action of putting on nice clothes leaves you feeling confident,happy,and attractive.Think about all of the different ways your own body language gives your own brain some important non-verbal clues.Sometimes it is really hard toforce yourself to change your body language.It may even feel as if you're “lying" to yourself a little bit.Despite these feelings,thereis nothing wrong about using non-verbal actions to build up your own confidence and self-esteem.Knowing how and when to do this is a powerful tool in dealing with the challenges and opportunities of daily life.Why does the author mention two different ways of walking across a room?

The notion that nothing good happens after midnight does not seem to apply to times of birth.Around the world the peak hours for births fall between I am and 7 am;the numbers then decrease throughout the rest of the day. This has led many scientists to believe that giving birth during the early morning offers some sort of evolutionaryadvantage,perhaps gained long ago when mothers and their infants would benefit from having their group reunited during the small hours to help with care and to defend them against animals.The problem with this theory is that almost all the information on the timing of human births comes from modern,urban settings,such as clinics and hospitals,which could produce artificial conditions that affect the variation in timings. Not so, it turns out.As Carlye Chaney shows in her research,early-morning births are common to communities with both modern and traditional lifestyles.The mothers that Ms Chaney chose to study live in a rural province in Argentina.They were divided into two groups that were considered to be both culturally and genetically distinct.One group consisted of 1,278 women from the Criollo population,a people of mixed Spanish and indigenous（本地的）heritage who live relatively modern lives and typically engage in farming.The second group was made up of 1,110 women who belonged to the Wichi and Toba populations，two of the traditionally nomadic（游牧生活的）peoples who also live there.If a modern way of life plays a part in favoring early-morning births,Ms Chaney speculated that she would see such timings dominate in the resuilts for the Criollo women,but feature less prominently among the results for the Wichi and Toba.Not so.The data and additional analysis make it clear that there is no statistical difference in the average birth time found between the two groups. Both showed a surge in births between 2 am and 3 am, and a big drop around 5 pm.More specifically,the average time of birth for the Criollo was 6.34 am and that for the Wichi and Toba was 4.18 am.Ms Chaney believes that the mechanism driving the tendency for mothers to give birth during the early morning is likely to be melatonin , a hormone which is known to increase at the start of labor（分娩）and is predominantly produced by the body between midnight and 5 am.That mechanism may well have comeabout,Ms Chaney suspects,because it was advantageous to go into labor when most help wasto hand.What do many scientists believe according to Paragraph 1?
