Life extension science(anti-ageing 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 ageing 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 "longevists" (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.
