Do you like to " read " other people's body language ? Our short guide will soon help you . Evidence about how we feel can often found in our hands and face , even if we try to hide it . For example , try asking a few people to smile at you . Can you tell if their smiles are genuine or fake ? No ? Look at the corners of their eyes , if small wrinkles can be seen then it be a " real " smile . If you can't see any wrinkles , it be a genuine smile . A good detective can also spot lies . If someone being honest , he / she can look you directly in the eyes . Another simple clue is that people often their mouth when a lie is told . As people get older , it's possible that they touch noses , rather than their mouth . Can you see people whose arms folded tightly across their chest ? This makes a barrer between them and the rest of the world . If people holding their arms , it's likely that they be feeling insecure . If someone has his thumbs up , you can be sure that he's feeling confident . However , if his hands are closed in tight fists , he's feeling angry , so be careful !
