Turning tendencies
Diagrams of Austrian physicist Ernst Mach's circa 1885 "turning tendencies" illustrations. [1].
In human chemistry, turning tendencies is a term used in circa 1885 by Austrian physicist Ernst Mach to describe the circular orbital movements of troops on dark nights. This is the same phenomenon as when people lost in the woods tend to return to their starting point. Some of Mach’s diagrams and drawings are shown adjacent. [1]

Human molecular spin
See main: Human molecular spin, human molecular orbital
In addition issue of field particle exchanges between individual humans, which constitutes the mechanism of force in the attachment or detachment of human chemical bonds, there is the issue of field particle exchanges between the earth and humans, i.e. between the earth molecule and individual human molecules attached to the earth's surface. [2] In short, whenever a charge moves, it creates a magnetic field that curls around the axis of its trajectory and when an external magnetic field is applied to a charge it causes the charge to curl in motion around the axis of the magnetic field. [3]

When this principle is applied to human life, the general effect is to cause human molecule to rotate differently depending on whether they are located north or south of the equator. At the North Pole, the earth’s magnetic field lines go into the ground; at the South Pole, the field lines come out of the ground. As a result of this, people tend to drive on the left hand side of the road in the southern portion of the earth and on the right side of the road in the northern portion. When Feynman diagrams are used to represent human molecular interactions, subsequently, a spin or curl pattern will develop within each system of interaction.
