The parts of our body are connected to each other. Each has its own purpose. Like our brain, it helps us control what to do in our daily routines. In connection to happiness, do you know that there is a little part in our brain that sends information to our heart whether we feel surprised, worried, dreaded or happy?This is the hypothalamus. It’s a tiny, sub cortical structure shaped like an ice-cream cone. Its bottom tip rests on the chickpea-sized pituitary gland, which it uses to link the nervous system with the endocrine system.

It is true that everything we feel, it comes from our heart. But before our emotion starts, the Hypothalamus processes it first. It is also the reason why our mood changes. To further explain this, let me give you the story of Phineas Gage.

He was a foreman in a railroad construction company. One day, he was excavating rocks to make way for a railroad track. He then used dynamites to make things easier. But tragedy struck him unexpectedly. When he detonated the dynamites, a tamping iron flew in the air and passed through his head; from his cheek to his brain. Fortunately, he survived the incident but his mood changed. According to the doctors, Gage’s case had confirmed findings that certain parts of his brain were affected. It gave evidence that his frontal cortex is involved in his personality because after the incident, the once jolly and quiet man suddenly became hot-tempered.

We sometimes say that we are not happy with our life. Happiness can be controlled by our mind. Our emotion is a state of mind.

It is the same as a heart transplant. Although the patient has changed his heart, his love never changed. Same with other kinds of emotion such as anger, anxiety, and happiness, it will always be there unless you try to forget it as it is controlled by the mind.
