"For every action, there is an equal and opposite reaction." FAB = -FBA
People do not realize what Isaac Newton's third law of motion really means.
Everything is balanced. Everything physical (matter/energy) goes back and forth in balanced circles, cycles, or the equivalent. Birth-death, old-young, big-small, strong-weak, start-stop, up-down, rich-poor, beginning-end, fast-slow, hot-cold, pain-pleasure, win-lose, day-night, full-empty, high-low, in-out, success-failure, united-divided, give-receive, creation-destruction, on-off, positive-negative, etc.
Positive and negative forces moving in balance are the physical universe.
There are no exceptions to the laws of nature Newton revealed. They apply to all matter and energy. Human beings are matter and energy, thus you and all humans are governed by the same laws.
