It is believed that a less massive star will age more slowly than a more massive star, despite the fact that massive stars have much more fuel. The reason that a more massive star will burn out quicker is because it takes a significant more amount of energy to keep the star burning due to the increased diameter of the star compared to the less massive star. A less massive star will use its fuel less quickly due to being smaller and having less mass to fuel.
The massive star burns its fuel at a greater rate than the less massive star.
The hypothalamic−pituitary−adrenal system helps maintain balance in the body by directing the sympathetic nervous system, as well as the endocrine system, immune system and digestive system. The hypothalamic−pituitary−adrenal system mainly controls the cortisol levels and the sympathetic nervous system, but it also plays a role in regulating hormones in the endocrine system, and it moderates the immune system and the digestive system.
