Longevity escape velocityIn the life extension movement, longevity escape velocity (LEV), actuarial escape velocity or biological escape velocity is a hypothetical situation in which one's remaining life expectancy (not life expectancy at birth) is extended longer than the time that is passing. For example, in a given year in which longevity escape velocity would be maintained, technological advances would increase people's remaining life expectancy more than the year that just went by.
Timeline of aging researchThis timeline lists notable events in the history of research into senescence or biological aging, including the research and development of life extension methods, brain aging delay methods and rejuvenation. People have long been interested in making their lives longer and healthier. The most anсient Egyptian, Indian and Chinese books contain reasoning about aging. Ancient Egyptians used garlic in large quantities to extend their lifespan.
Outline of life extensionIndex of life extension-related articles The following outline is provided as an overview of and topical guide to life extension: Life extension – study of slowing down or reversing the processes of aging to extend both the maximum and average lifespan. Also known as anti-aging medicine, experimental gerontology, and biomedical gerontology.
Life extensionLife extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled limit of 125 years. Several researchers in the area, along with "life extensionists", "immortalists" or "longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans (agerasia) through complete rejuvenation to a healthy youthful condition.
ImmortalityImmortality is the concept of eternal life. Some modern species may possess biological immortality. Some scientists, futurists, and philosophers have theorized about the immortality of the human body, with some suggesting that human immortality may be achievable in the first few decades of the 21st century with the help of certain technologies such as mind uploading (digital immortality). Other advocates believe that life extension is a more achievable goal in the short term, with immortality awaiting further research breakthroughs.
RejuvenationRejuvenation is a medical discipline focused on the practical reversal of the aging process. Rejuvenation is distinct from life extension. Life extension strategies often study the causes of aging and try to oppose those causes in order to slow aging. Rejuvenation is the reversal of aging and thus requires a different strategy, namely repair of the damage that is associated with aging or replacement of damaged tissue with new tissue. Rejuvenation can be a means of life extension, but most life extension strategies do not involve rejuvenation.
Human enhancementHuman enhancement is the natural, artificial, or technological alteration of the human body in order to enhance physical or mental capabilities. Three forms of human enhancement currently exist: reproductive, physical, and mental. Reproductive enhancements include embryo selection by preimplantation genetic diagnosis, cytoplasmictransfer, and in vitro-generated gametes. Physical enhancements include cosmetics (plastic surgery and orthodontics), Drug-induced (doping and performance-enhancing drugs), functional (prosthetics and powered exoskeletons), Medical (implants (e.
BiogerontologyBiogerontology is the sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. The term "biogerontology" was coined by S. Rattan, and came in regular use with the start of the journal BIOGERONTOLOGY in 2000. It involves interdisciplinary research on the causes, effects, and mechanisms of biological aging. Biogerontologist Leonard Hayflick has said that the natural average lifespan for a human is around 92 years and, if humans do not invent new approaches to treat aging, they will be stuck with this lifespan.
TranshumanismTranshumanism is a philosophical and intellectual movement which advocates the enhancement of the human condition by developing and making widely available sophisticated technologies that can greatly enhance longevity and cognition. Transhumanist thinkers study the potential benefits and dangers of emerging technologies that could overcome fundamental human limitations, as well as the ethics of using such technologies.
