It is well known that the underlying mechanisms of osteoporosis in older adults are different than those associated with estrogen deprivation. Age-related bone misfortune includes a steady and dynamic decrease, which is likewise found in men. Uniquely expanded bone resorption prompts the underlying fall in bone mineral thickness. With expanding age, there is likewise a huge decrease in the bone arrangement. This is for the most part because of a move from osteoblast genesis to dominating adipogenesis in the bone marrow, which likewise has a lipotoxic impact that influences lattice development and mineralization. Life extension science(anti-aging medicine) can also be termed as uncertain life augmentation, exploratory gerontology, and biomedical gerontology is defined as the investigation of slowing down or reversing the procedures of aging to broaden both the most extreme and normal life expectancy. The capacity to accomplish this, be that as it may, does not presently exist. A few specialists around there, and "life extensionists", "immortalists" or "longevity" (the individuals who wish to accomplish longer lives themselves), trust that future breakthroughs in tissue restoration, undifferentiated cells, regenerative drug, sub-atomic repair, quality treatment, pharmaceuticals, and organ substitution (for example, with artificial organs or xenotransplantations) will, in the end, enable people to have inconclusive life expectancies (agerasia) through complete rejuvenation to a well youthful condition. The moral implications, if life augmentation turns into a possibility, are argued by bioethicists. The expansion of life has been a want of mankind and a pillar theme ever.
