Are there any shortcuts to a long life?

Well, some people like Meredith Averill, 61, and her husband, Paul McGlothin, 60, believe they may have the answers and they're putting themselves to the test in their quest for longevity.

The couple have been practicing calorie restriction for the last 14 years. Calorie restriction is the only proven way to extend life in animals and, now, studies are getting started in humans.

Averill and McGlothin are the subjects of one such study. As calorie restrictors they eat only specific amounts of foods that are high in nutrition but low in calories -- foods like vegetables, fruits and beans.

Introduction to Human Growth Hormone (HGH)

I am an adult male and became fascinated with Injectable HGH in 2003 by a twist of fate.  It occurred after I met one of my neighbors and became friends with him, not to mention he later got me a job teaching part time at one of the universities where he was working!  

My friend, Dr. W, is a University Professor who has a resume spanning over 40 years teaching at prestigious universities, all over the world. What caught me off guard was the fact Dr. W claimed he was in his mid 60’s, but didn’t look even close.  He wouldn’t tell me his exact age, yet he had the energy, a lust for life, and the vitality of an athletic man in his early 30’s.  I found it strange, even bizarre, as he honestly didn’t look a day older than 37.  

While aging processes can be divided into three general categories -- genetic, biochemical, and physiological, theories of aging fall into two categories.

The "programmed" theories hold that aging follows a biological timetable, perhaps a continuation of the one that regulates childhood growth and development. The damage or error theories emphasize environmental assaults to our systems that gradually cause things to go wrong. It's important to note, many of the theories of aging are not mutually exclusive.

Here is a brief and very simplified rundown of the major theories.

Programmed Theories

• Programmed Senescence. Aging is the result of the sequential switching on and off of certain genes, with senescence being defined as the time when age-associated deficits are manifested.
• Endocrine Theory. Biological clocks act through hormones to control the pace of aging.
• Immunological Theory. A programmed decline in immune system functions leads to an increased vulnerability to infectious disease and thus aging and death.
  

Error Theories

• Wear and Tear. Cells and tissues have vital parts that wear out.
• Rate of Living. The greater an organism's rate of oxygen basal metabolism, the shorter its life span.
• Crosslinking. An accumulation of crosslinked proteins damages cells and tissues, slowing down bodily processes.
• Free Radicals. Accumulated damage caused by oxygen radicals causes cells and eventually organs to stop functioning.
• Error Catastrophe. Damage to mechanisms that synthesize proteins results in faulty proteins which accumulate to a level that causes catastrophic damage to cells, tissues, and organs.
• Somatic Mutation. Genetic mutations occur and accumulate with increasing age, causing cells to deteriorate and malfunction.
