Some body language has many different uses. Perhaps the best example is smiling. A smile can help us get difficult situations and find friends in a world of strangers. A smile can down barriers. We can use a smile to apologise, to greet someone, to ask for help, or to start a conversation. Experts suggest at yourself in the mirror to make yourself feel happier and stronger. And if we are feeling down or lonely, there is nothing better than seeing the smiling face of a good friend.
