There is constant exchange of magnetism between you and your surroundings and people with whom you come in contact. For example, on meeting someone, you may become aware that something is happening to you, you are actually receiving a current from that person. In order to receive another’s magmatism, you must be near him.
When you shake hands with someone, a magnet is created, and you exchange magmatism. If you are more powerful or positive one, you will give the other person your vibrations, but if are weaker, you will receive his vibrations. This explains why people unconsciously like to shake hands of famous men and women.
