Women aren't the only ones seeking a cure for aging. Science is one step ahead of them, both seeking the reasons for aging and finding answers. Several companies are devoted to reversing the aging process in order to prolong youth as long as possible.

Sierra Sciences is busy exploring the possibility of extending life past 125 years. According to Sierra Science, aging occurs because of shortened telormerases, enzymes found in cells. Reproductive cells don't experience shortening, and thus don't age. Based on this information, Sierra Science is working on identifying what shortens telormerases, and looking for ways to induce telormerase production in all body cells. The theory goes that in order to stop the aging process it is necessary to increase the amount of telormerase in the cells of the body to make them appear younger.

While ways to increase telormerase in the body remain a mystery, there are other scientific breakthroughs in anti-aging already being used. One of these methods is DPL LED light therapy, which diminishes physical signs of aging. The FDA approved system relies on energy from light to dramatically reduce the appearance of aging. The idea is to restore the skin to a more supple state by activating fibroblasts, which in turn increase collagen and elastin.

When coupled with diet and exercise, Bioidentical Hormone Therapy is another scientific breakthrough in anti-aging. Bioidentical hormone therapy seeks to help both men and women live longer, healthier lives. This therapyis based on the principle that having your hormones out of balance can affect other aspects of health as well. By treating out of balance hormones with bioidentical hormone therapy, you can help restore the lost energy and vitality that comes with aging.

One anti-aging trick that won't cost you a cent is known as calorie restriction. Not only can it add as many as five years to the human lifespan, but it may also help prevent serious diseases like cancer, diabetes and heart disease. Scientists aren't sure why calorie restriction is so effective in anti-aging, but they are hypothesizing that it may have to do with lowering the metabolic rate, thus generating fewer damaging "free radicals." It may also decrease thyroid hormone, triodothyronine (T3), which in turn slows the metabolism and tissue aging.

While science continues to make advances in the anti-aging movement, eating right and exercising remain the cornerstones of unchanging youth and healthy living.
