picture above is wrong as the muscles in the face start to sag and loose its tightness as we grow old. Old age has nothing to do with fatty white tissue decreasing in face.

Well after careful analysis and research. I came to one conclusion and that conclusion should be a valid conclusion. Upon doing a research scientist do not know what causes aging, they literally have no clues no specific leads but just thousand of theories that usually are proven wrong from time to time. One of their best guess is that Scientist claim that the blood cells copy each other thru out development from birth to old age to death. They claim that out time clock of youth development stops by 30 and that our time clock reverses from getting young to becoming old after age 30. They claim that the blood cells start copying less and less of each other as we grow into each decade in our lives after 30.
But after carefully thinking about this logically my conclusion came to this. How do we age in the first place since our birth? Well the answer is clear every human goes thru puberty Every child has to go thru puberty to become an adult. But puberty isn't just one time process in a child's teenagers year because our pituitary glands actually control our aging process and our human develop process form child to adult since child birth. That the pituitary glands are responsible for child grow and development but without it a child/baby would never be able to grow at all.
What humans perceive as being young isn't really young but a process in which the pituitary glands are making the body going thru a process transformation from a baby to adult. It is this same pituitary glands that are releasing chemicals to actually break down the body causing old age after 30 yrs old. It could be two things that the pituitary glands are releasing chemicals or that the pituitary glands slowing dying off releasing less chemicals thus causing the aging process the break down of bones, muscles, blood cell, tissue.
The pituitary glands start off the aging and development process since child birth, its the organ that is responsible for transforming a baby into a child into a adult and it has to be same organ responsible for old age as the pituitary glands releases chemicals for these developments during child birth to adulthood.
One thing for certain is the pituitary glands morph a baby into an adult. In honestly a child evolves into an adult because of the pituitary glands but what
i'm discussing here has nothing to do with evolution but actually morphing of a baby into an adult by growing its body. Read below more to learn what the pituitary glands actually do.
The pituitary glands produce these hormones
  • Adrenocorticotrophic hormone (ACTH)
  • Thyroid-stimulating hormone (TSH)
  • Luteinising hormone (LH)
  • Follicle-stimulating hormone (FSH)
  • Prolactin (PRL)
  • Growth hormone (GH)
  • Melanocyte-stimulating hormone (MSH)

Where is my pituitary gland?

Computer artwork of a person's head showing the left hemisphere of the brain inside. The highlighted area (centre) shows the pituitary gland attached to the bottom of the hypothalamus at the base of the brain.
The pituitary gland is a small gland that sits in the sella turcica (‘Turkish saddle’), a bony hollow in the base of the skull, underneath the brain and behind the bridge of the nose. The pituitary gland has two main parts, the anterior pituitary gland and the posterior pituitary gland. The gland is attached to a part of the brain (the hypothalamus) that controls its activity. The anterior pituitary gland is connected to the brain by short blood vessels. The posterior pituitary gland is actually part of the brain and it secretes hormones directly into the bloodstream under the command of the brain.

What does my pituitary gland do?
The pituitary gland is called the 'master gland' as the hormones it produces control so many different processes in the body. It senses the body's needs and sends signals to different organs and glands throughout the body to regulate their function and maintain an appropriate environment. It secretes a variety of hormones into the bloodstream which act as messengers to transmit information from the pituitary gland to distant cells, regulating their activity. For example, the pituitary gland produces prolactin, which acts on the breasts to induce milk production. The pituitary gland also secretes hormones that act on the adrenal glands, thyroid gland, ovaries and testes, which in turn produce other hormones. Through secretion of its hormones, the pituitary gland controls metabolism, growth, sexual maturation, reproduction, blood pressure and many other vital physical functions and processes.

What hormones does my pituitary gland produce?
The anterior pituitary gland produces the following hormones and releases them into the bloodstream:

  • adrenocorticotropic hormone, which stimulates the adrenal glands to secrete steroid hormones, principally cortisol
  • growth hormone, which regulates growth, metabolism and body composition
  • luteinising hormone and follicle stimulating hormone, also known as gonadotrophins. They act on the ovaries or testes to stimulate sex hormone production, and egg and sperm maturity
  • prolactin, which stimulates milk production
  • thyroid stimulating hormone, which stimulates the thyroid gland to secrete thyroid hormones.
Each of these hormones is made by a separate type of cell within the pituitary gland, except for follicle stimulating hormone and luteinising hormone, which are made together by the same cell.

Two hormones are produced by the hypothalamus and then stored in the posterior pituitary gland before being secreted into the bloodstream. These are:

  • anti-diuretic hormone (also called vasopressin), which controls water balance and blood pressure
  • oxytocin, which stimulates uterine contractions during labour and milk secretion during breastfeeding.
Between the anterior pituitary and the posterior pituitary lies the intermediate pituitary gland. Cells here produce:

  • melanocyte-stimulating hormone, which acts on cells in the skin to stimulate the production of melanin.
What could go wrong with my pituitary gland?
The pituitary gland is an important gland in the body and the hormones it produces carry out varied tasks and regulate the function of many other organs. This means that the symptoms experienced when the pituitary gland stops working correctly can be different, depending on which hormone is affected.

Conditions that affect the pituitary gland directly can be divided into three main categories:

  1. Conditions that cause the pituitary gland to produce too much of one or more hormone(s). Examples include acromegaly, Cushing's disease and prolactinoma.
  2. Conditions that cause the pituitary gland to produce too little of one or more hormone(s). Examples include adult-onset growth hormone deficiency, diabetes insipidus and hypopituitarism.
  3. Conditions that alter the size and/or shape of the pituitary gland. Examples include empty sella syndrome.
A cell type may divide and then form a small benign lump, known as a tumour, and the patient may then suffer from the effects of too much of the hormone the cell produces. If the tumour grows very large, even though still benign, it may squash the surrounding cells and stop them working (hypopituitarism), or push upwards and interfere with vision – a visual field defect. Very occasionally, the tumour may expand sideways and cause double vision as it affects the nerves that control eye movements. It should be emphasised that even when these tumours are large, they very rarely spread to other parts of the body.
