What is Aging?
From the physical point of view, human aging is a process of cumulative changes, both morphological and physiological, resulting in a progressive diminution of our body and organs ability to defend from external aggression and to adapt to changing conditions.
There are many factors contributing to aging, but I will discuss three that are inherent to our body functioning. They are a natural outcome of our normal metabolism.
Free Radicals.
Free radicals are highly reactive molecules with an imbalance on their number of electrons. They are a sub-product of the energy generation process within our cells. This imbalance makes them react with our cells modifying their normal functioning.
Energy generation is a fundamental

If you take a human fibroblast ( a type of cell) belonging to a child, it will divide itself around 60 times and it will stop proliferating. The same type of cell from a 40-year-old man will only divide around 40 times while in an 80-year-old man it will only divide around 30 times.
At that moment the fibroblast is detected as a damaged cell and it dies. It is a defense mechanism stopping damaged cells to reproduce, thus increasing tumor and cancer risk, but in the long run there is a progressive diminution of this response and the body will support an increasing number of malfunctioning cells.
Healthy Aging.
As we have just seen, stronk aging factors work from the inside. The way it looks, chances are science will not be able to to stop the process. So what can we do about it. The answer is Healthy Aging, a lifestyle allowing us to grow old while maintaining the best possible health condition.
It is only reasonable to think that if we decrease the aging factors the result will be a slower aging so let's discuss some ways to achieve that.
Free Radicals
A good way to slow down the aging process is to restrict the ingest of calories by eating more fruits and vegetables. This is a very effective method mainly
To slow down the aging process, you can alter things in your everyday life, for example smoking which is an extrinsic factor. Dr. Milton Moore, a Houston-based dermatologist says
Humans are born already aging. There is know way to stop the process of getting older. As people age it is important that services and rescores are set up to
The aging process in late adulthood is called senescence. People cannot stop the effects of aging but there are alternatives that can help ease the process. These measures are not always followed because people make poor life choices such as smoking. Aging adults will even spend millions of dollars trying to slow the process of aging. No matter how much money they spend aging will occur.
It is a known fact that all measures of physiological function decline in human aging. While genetics certainly play a role in the declining of physiological function with age, it can be argued that a fundamental part of aging can be reflected by chemical processes resulting in the appearance of harmful side products of the normal metabolism over time. When enzymes speed up reactions it is harder to slow them down. At the same time side reactions are constantly occurring and more and more unwanted side products are continuously being formed.
(1) The theory that best support my current views on aging is the Wear-and-Tear Theory. The theory is “the idea that changes associated with aging are the result of chance damage to the body that accumulate over time”. (2) As many of us know, the body is constantly renewing itself. The cells in you is constantly creating new ones to replace the old, just like a boat. You are constantly restoring all the parts, where the boat will basically be almost all new parts. I think our body is like a built boat, car, or even a house, you must keep repairing it. Some people would literally get a new body part. A blood transfusion, heart replacement and a leg replacement are some examples of the theory. But just like a used car, boat or house, we stop
Normal aging is a gradual decline in certain processes (Gladyshev, & Gladyshev, 2016). The decline is not static and can be increased or reduced depending on choices made (Gladyshev, & Gladyshev, 2016). Changes commonly attributed to aging include declines in the five senses, most organ systems, appearance and brain function (Tully, 2016). The five senses include reduction in taste buds, smell, ability to hear high frequency sounds and speech discrimination, reduced ability to see in the dark and a reduction in tactile sensory (Tully, 2016). In the organ systems there is a reduction in the hearts response to work, bone mass, skin turgor, vital capacity in the lungs, renal and colon function (Tully, 2016). Most notable is the age-related changes
Aging is the amount of changes in person overtime. It is a multidimensional process, which can affect a person physically and psychologically. With age, people weaken and affect their memory. There are four types of aging: intrinsic, universal, progressive and deleterious. Intrinsic aging is chronologic aging, it deals with internal factors, and it decreased fat cells size, and damaged fat cells differentiation. Deleterious aging connects with aging will only be considered as part of the aging process if it “poor” for the individual. Universal aging deals with the process of how aging occur differently in all individual of species.
Interestingly enough, one of the major factors that speed up the process of aging is
This theory is called the Cellular Aging where “the cumulative effect of stress and toxins, [are] causing first cellular damage and eventually the death of cells” (Berger 690). Fortunately, these causes of aging can be modified through eating foods rich in antioxidants to reduce the damage created by free radicals, and practicing mental fitness to keep the brain sharp. Calorie-Restriction, the method of "limiting dietary energy intake . . . while consuming sufficient quantities of vitamins minerals and other important nutrients . . . [can also slow cellular aging]" (Berger 691). However, Berger states that such method does not work for everyone because the specifics of diet are crucial. Restricted-diet might help other creatures, but it doesn’t guarantee that it will slow down the human aging
why and how we age, and how to possibly slow the aging process. As we age, innumerable
Everyone wants to stop the process of aging and man has been in search of a product that will help him. A few years ago, researchers found that aging occurs due to the reduction in production of the Human Growth Hormone in the body. As the body ages, the pituitary glands, responsible for the production of HGH, do not produce sufficient quantity of the hormone causing the many signs of aging to appear.
The authors are thus led to conclude that “to date, no convincing evidence showing the administration of existing ‘anti-aging’ remedies can slow aging or increase longevity in humans is available.” And the SENS Research Foundation Web site admits: “No currently-available medical intervention or lifestyle choice has been shown to affect the basic human aging process.”"
While anti-aging is a field of interest, there are some challenges that come about since aging is a complicated process with no definitive answer. Due to factors
All the best information on fitness exercise workouts programsAging and Its Many ProblemsThe metabolism of your body dramatically slows down as you reach your middle ages. This is neither an excuse nor a myth, but a plain and simple fact! Fortunately for you, there are several ways that can be done in order for you to reverse the impacts of aging. Then again, it is best first that you have an idea as to why this decrease in your body’s metabolism occurs. Take a look at some of the common reasons.
Aging is the process of becoming older, as we age, multiple mutations occur that concern all the processes of aging well as it compromising a number of different genes. There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a “biological clock that determines its maximum life span” and how quickly one 's health will deteriorate(Hooyman, 42). After a certain number of years, each cell which follows an apparent biological clock starts to replicate itself less, thus the specific individual or species slowly deteriorates. This theory gives
