REJUVENATION THE INTRODUCTION BY JOHN HUBBELL

We start aging the moment we are born - If you are alive, you are aging - you can not avoid it. To understand aging we have to understand what impacts on our ageing process. I have listed below under the title ‘The Effects Of Aging’, some of the accepted aging processes. We all age differently we are individuals, therefore in our life time, even if we treat out bodies like temples we will still all have to individually deal with some of these known aging processes. If you have NOT looked after yourself then you will accelerate some of these process and aged prematurely.

I define the concept of slowing and with some processes reversing the aging process as REJUVENATION. Rejuvenation is based around the concept of Biological Age, which I am studying and presenting a PhD thesis on.
With biological age you can have a person entering middle chronological age say 40 years who has an advanced biological age say 70 and vice versa you can have a chronological age of 70 that has a more youthful biological age of 40.

Biological age is the comparison of our body’s wellness status in relationship to the status of a specific population’s chronological age which is the same as ours. Traditional biological age measurements compare physiological activities, body composition, mechanical functionality and psychological health. The main factors that affect ones biological age are environment, life style and genetics.
Scientific studies have proven that in today’s world, life style and environment plays a far more significant role in aging than do genetics. In the last two centuries, there has been a dramatic increase in our lifespan. This proves that aging and life span are not processes that are fixed. This also proves that the extension of life span, through the reduction of biological age is possible by manipulation of our environment and life style..

We can slow and reverse the aging process. We can improve our health by changing our maladaptive behaviours and / or our surroundings to start reversing the damage and renew our health. Our strength, flexibility, cardiovascular and power fitness can improved at every age, joints rebuilt, mobility enhanced, energy revitalized and nutrition can be used to compensate for metabolic changes that come with age, this is the process of REJUVENATION.

The degree to which one can rejuvenate oneself fits on a spectrum of potential achievement. Rejuvenation is very dependent on the time, commitment, motivation and the resources that one whishes to apply to the process. Nutrition and movement are the two factors one needs to manipulate to experience rejuvenation. Therefore, at one end of the rejuvenation spectrum one can simply eat well and move so that there is minimum positive benefit to their health, or at the other end of the spectrum train like an Olympic athlete, in regards to time, scientific training methods and nutrition.

THE EFFECTS OF AGING

Aging is universal and happens to all of us. The list of age related degeneration listed below is only a brief description of the many aging issues, but a scary list just the same. However, it is a fact that that exercise and nutrition can delay the onset and in some cases eliminate the onset of most of these aging effects. Knowing how and why your body changes with age will help you discourage alterations in cell, tissue, and organ function that slow you down. Most age related changes go unnoticed, even for decades. Aging affects all our body functions and structures if we do not look after ourselves then we will accelerate the following ageing processes:

Anatomical Effects: As we age bones get thinner making us more susceptible to fracture. Joints become less resistant to wear and tear. Aging causes a decrease in the strength, size, and endurance of muscle tissue. Dermal and epidermal cells diminish, causing easier bruising and tearing more easily and taking longer to heal and increase in our vulnerability to infection.

Cardiovascular Effects of Aging: Aging brings on increased stiffness of the chest wall diminishing blood flow through the lungs and a reduction in the strength of your heartbeat. Blood vessels change by slowly thickening and become less elastic, increasing their vulnerability to normal wear and tear. Older people take longer to recover from stress, a shock, or surprise. After exertion, such as exercise, more time passes before their bodies return to a normal resting heart rate and blood pressure. Older people often feel colder than their younger counterparts, largely due to diminished circulation.

Gastronomical Effects of Aging: As you age: chewing can become more difficult, your esophagus doesn't contract as forcefully, you do not produce enough stomach acid, you have a narrowing of the bile duct, your production of digestive enzymes decrease, your intestines become thinner and sluggish, your liver and kidneys gets smaller. All these facts cause faulty food absorption and body functioning, resulting in many negative gastronomical issues.

Immunological Effects of Aging: Aging decreases immunity by impairing the body's production of antibodies increasing the body’s susceptibility to autoimmune diseases such as rheumatoid arthritis or lupus.

Metabolic Effects of Aging: Beginning around age 25, total body fat starts to increase, while muscle mass and body water decrease. Combining this with a decrease in activity level, you may weigh more as you age. In addition, the expansion of your trachea contributes to a decreased surface area in your lungs, lung capacity and function drop off with time. Diminishing your ability to clear germs from your lungs, putting one at higher risk of infection.

Sensory Effects of Aging: Aging can also play havoc on your five senses: eyesight, hearing, taste, smell and touch.
