Handshake analysis

The handshake has its roots in the deep past. When primitive people met in a peaceful atmosphere, they showed palms to each other to show that they did not hide any weapons. During the time of the Roman Empire, the habit of hiding a dagger in a sleeve became so common that the Romans developed a wrist grip at belt level, which has become a common greeting.
Nowadays, the grip of the wrist has been transformed into a handshake. Such a gesture began to be used in the XIX century when concluding commercial transactions between people of equal status. It became widespread only in the last century. Until recently, only men shook hands. In most European countries and in America, a handshake is a greeting and farewell in any office setting. Handshake at parties and social events has become increasingly used. Today, it is permissible to shake hands with women.
The grip of the wrist at the waist level is a demonstration of the absence of hidden weapons. This is a typical Roman greeting.

A handshake held together commercial deals between men.

Even in countries such as Japan, where the traditional greeting is a bow, or Thailand, where the bow is accompanied by almost prayer folding hands, today you can often face the usual handshake. In most countries, the hand is shaken five to seven times, but in some places, for example, in Germany, only two or three times, after which the arm is held for a time equivalent to two shakes. The French shake hands most often - at each meeting and at each separation.
