What is the scientific method for achieving health and longevity?

According to the research conducted by the Ohio State University, the mental stress hormones of cartisol leukins and interleukins have inter-relationship with each other. It is the inter-leukins

that controls the infectious diseases. An increased presence of cartisol lessens the inter-leukins chemical’s presence and results in diseases. Scientifically speaking, a calm mind cures and heals injuries quickly. It is the inter-leukins that keeps a man happy, healthy and free from diseases.
During exercise, the body produces a hormone called endorphins that dispels the mental fatigue and keeps us healthy and happy. Hence, when exercise is observed daily, the endorphins secrete more and
thus we remain happy. Further, these enzymes reduce the fat content in the blood and protect us from diseases, particularly the heart-related ailments. A one hour walk rejuvenates us and destroys the fat
deposited on the walls of blood vessels paving for a smooth flow of the blood to the body. The mental fatigue results in various afflictions that include irritation, rashes, pimples

and scars on the skin and in women, stoppage of menses release. Further, mental fatigue in pregnant women results in premature delivery of the baby and the subsequent palpitation increases the blood pressure that may end up in chest pain and other heart-related problems. The main cause for all these lies in the hypothalamus gland of the brain, which is responsible for the production of fight or flight response which is opposite of relaxation response in our body and activates the pituitary gland.
