As one of few proven methods of anti aging that work, caloric restriction is being widely implemented at present, the research on any pharmaceuticals that can somehow mimic the caloric restriction effect continues. In fact, a huge number of some potential CR-mimetics are actually under study. Moreover, the most common and most available one is Resveratrol since it can be easily purchased over the counter of pharmacies. It was in the year 2003 when the Life Extension Foundation decided to fund some gene-chip research experiments just so scientists can compare the gene expression in some calorically-restricted test animals with those of the test animals that are given different prescription drugs. According to the end results of such experiments, Resveratrol extended the lifespan of test animals as it reduced the aging process. Moderate exercise Performing mild exercise has been proven to have some protecting effects against possible system failures. In fact, elderly people who exercise become generally less frail, much less susceptible to bone fractures, or other highly unexpected catastrophes. Strength training has been proven to have the largest effect there can possibly be in the matter of life extension. Since the flexibility and aerobic training is able to help against fragility, the negative effects of aging are somehow opposed, and the life is further extended by approximately two percent. However, with heavy exercise, the lifespan of the test animals were shortened by as much as five percent, but lengthens the average lifespan. This can be related to the scientific results that say that stem cells are much more attracted to the cytokines that are naturally released from the body due to mild damage that is usually the effects of mild damage. The science of cryonics Majority of those who are interested in the process life extension are very much interested in cryonics as well. This particular field of science is actually a known alternative to certain deaths that are brought about by age-related damage. The disadvantage of this field is that it can only be availed through a costly purchase, which can be amounted to as much as thirty to one hundred and twenty thousand dollars. Usually, cryonics is funded by life insurance companies. But, still, the amount that needs to be paid is usually impractical, especially for the elderly and the unhealthy individuals. Cosmetic surgeries Other procedures that clients can perform to create a youthful appearance are the different kinds of cosmetic surgery. This particular branch of surgery is actually a large industry that offers different kinds of treatment methods such as the removals of wrinkles, which can be done via face lift, the removal of extra fats, more popularly known as liposuction, or by the reshaping or augmentation of the person's different body parts, usually the breasts, abdomen, and face. This is a procedure when the aging process is intentionally reversed, which, in turn, brings back the youth. When people get older, their health naturally worsens, the intelligence and the strength start to diminish, and the beauty fades away.
