To start, lobsters and humans have similar nervous systems and live in a dominance hierarchy. But what do lobsters have to do with standing up straight? Well, humans and lobsters share the chemical serotonin, which governs posture. When a lobster is defeated in a fight, its posture drops, it faces the ground and appears weak to others. The same thing happens to humans, and with each defeat, serotonin levels drop and so does our posture.
If a person slouches, they present themselves as defeated. However, if a person stands up straight, it means they may have taken a hit but are not defeated.
It means that you, both physically and mentally, are able and willing to move forward in life to the next challenge. It also signals to other people that you are able to handle whatever life throws your way while you pursue your rightful destiny.
Life is not easy. There will be pain and suffering. But do not let chaos bring you down. Accept the fact that this journey will not be smooth and that no matter what happens, you will take responsibility for your life and do what you can to make it better. And when negative situations occur in life that you cannot control, you will still stand up straight and not let it bring you down.
