Transhumanism

Transhumanism is an intellectual and cultural movement with the idea that humanity is capable of and should fundamentally alter the human condition with the use of emerging technologies, and make these modifications widely accessible. These modifications of the human condition are the elimination of aging and the enhancement of intellectual, physical, and psychological capabilities.

Preservation
Some individuals opt to preserve their brains, and sometimes entire bodies, through means such as cryonics. Other options for preservation include plastination. Another technology being developed is chemical brain preservation.

The rationale behind preserving one's brain is the idea that consciousness is stored within the material structure of the brain. With the brain preserved, in the future, preserved individuals could possibly be revived with the use of future technologies.

Technologies of interest
An emerging technology that is being developed today is genetic engineering. In the future, humans could use it to modify their own genotypes, and therefore increase their physical and cognitive ability.

Another emerging technology of interest is nanotechnology. Nanotechnology could allow damage to the body to be repaired on a microscopic level. Nanotechnology also allows for the development of nanometerials such as carbon nanotubes.
