What causes AGE?

Answer 1

Answer:

Each cell in your body has a countdown clock that limits the number of replications that it can undergo. This clock is the telomere, a region of repetitive DNA at the end of each chromosome. Each time the cells divide a part of the telomere is lost. When enough telomere is gone the division starts cutting into the chromosome itself. Important genetic information is lost and the cell dies. When enough cells die, you age and die.

On the down side, when cells ignore the loss of the telemeres and don't die, they become cancerous and you die.

Biologists feel that this telemere countdown is a tradeoff between aging and cancer.

Answer:

There are two types of aging for the skin. There is the intrinsic (internal) aging, which is caused by factors within your own body, such as genes and body condition; and extrinsic (external) aging, which is caused by factors outside your body, such as sunlight and lifestyle.

Intrinsic (internal) aging

On average, signs of skin aging begin to appear in the mid-20s. As you grow older, the skin's ability to snap back to shape (elasticity) starts to decrease. That is because skin cells do not regenerate as fast as they used to - resulting to tougher, older skin. Although internal aging begins in one's 20s, the typical signs of wrinkles and sagging skin do not appear for until about a couple of decades more. Other signs that indicate skin aging are thinning, loss of firmness, dryness, and reduction of sweat production that prevents proper cooling of the body.

Extrinsic (external) aging

Factors outside your own genes accelerate skin aging. Lifestyles and habits carry more impact of why aging skin occurs more prematurely in your lifetime. With the present condition our atmosphere is in, harmful rays from the sun pass through in ever increasing amounts causing damage to the skin and hampering its ability to repair itself. Over a period of time, a few minutes a day of exposure to ultraviolet rays results in changes to the skin (freckles, age spots, rough skin).

Cigarette smoking does not only cause harm to the body internally but externally as well. This is most pronounced with the condition of the skin. Nicotine intake causes changes in the body that speeds up the break down of skin cells, among other harmful effects. Drugs and stress.

Answer

A major contribution to the symptoms of aging is that our glands get old, producing les testosterone, HGH and other "youth" hormones. Diet, exercise and supplements can jncrease testosterone and HGH levels. DHEA and Tribulus, for example can reduce the age related decline in testosterone. A high protein diet and strength training can increase HGH and test. levels.
