Anti-aging movement
The anti-aging movement is a
There are many scientists of this movement with different approaches. Two of the most popular proponents of the anti-aging movement include Ray Kurzweil, who says humanity can defeat aging through the advance of technology, allowing us to reach the longevity escape velocity,[4] and Aubrey de Grey, who says that the human body is a very complicated machine and, thus, can be repaired indefinitely.[5] Other scientists and significant contributors to the movement include molecular biologists, geneticists, and biomedical gerontologists such as Gary Ruvkun, Cynthia Kenyon, and Arthur D. Levinson. However, figures in the gerontology community in 2003 tried to distance their research from the perceived pseudoscience of the movement.[6]

Senolytics
A senolytic (from the words senescence and -lytic, "destroying") is among a class of small molecules under basic research to determine if they can selectively induce death of senescent cells and improve health in humans.[17] A goal of this research is to discover or develop agents to delay, prevent, alleviate, or reverse age-related diseases.[18][19] Removal of senescent cells with senolytics has been proposed as a method of enhancing immunity during aging.[20]
A related concept is "senostatic", which means to suppress senescence.[21]Scientific approaches
Biogerontology is a scientific discipline which has the same area of interest but, as a branch of gerontology, takes a more conservative approach.[22] Caloric restriction is a phenomenon introduced in anti-aging techniques which focuses on depletion of calories and taking the right amount of nutrients necessary for growth.[23]
Calorie restriction
Calorie restriction (CR) refers to a dietary restriction that focuses on less calorie intake to increase longevity and reduce

Reception
There are at least two opposite views on the prospects of anti-aging research and development. One group states that there is a great deal of over-heated rhetoric in use with respect to life extension with over-optimistic projections by its advocates. They also claim that there is little evidence that any significant breakthrough has been made, or is on the horizon.[31] Some state that this is largely due to a current lack of funding or interest in the issue.[32] A study of the commonly-used supplements and hormone treatments published in 2006 in the Cleveland Clinic Journal of Medicine showed that none of them are effective for extending life.[33] Another group notices that recent scientific successes in rejuvenation and extending the lifespan of model animals[34][failed verification] and discovery of a variety of species (including humans of advanced ages) having negligible senescence give hope to achieve negligible senescence (cancel aging) for younger humans, reverse ageing, or at least significantly delay it.
Though some scientists think curing aging is impossible, there are some criticisms of both the time frame life extensionists envision (the first, perhaps somewhat crude, treatments within the next several decades, or at least before the beginning of the 22nd century) and of whether curing aging is even desirable. Common criticisms of the idea of life extension are fears it will cause the world to be more

There have been a number of social movements associated with the reappraisal of age-based social categories in the last thirty years. Two such developments are the focus of this chapter. They are the Third Age movement and the Anti-aging movement. These movements present contrasting perspectives on the culturally devalued status of old age; the former seeks to celebrate old age, the latter to eliminate it.

Maybe it is because of his background in computer science that Dr. de Grey perceives the human body as a very complicated machine. Therefore, he argues that aging is primarily an engineering problem. Thus once we grasp all the finer details of our biological structure then the problem of aging becomes one of maintenance and just like today we are capable to maintain vintage cars or airplanes indefinitely he believes that eventually we'll be able to do so with our bodies.

Leading members of the gerontological community have recently launched a war on anti-aging medicine, seeking to discredit what they judge to be fraudulent and harmful products and therapies, and to distinguish their research from what they regard as the pseudoscience of the anti-aging movement.
