Longevity is not guarantee happiness, but many people still do not feel satisfied with the allotment of their age in the world. Various attempts were made in order to make the age so much longer, beginning from technology to modify the body's cells to multiply human.
Death is inevitable. However, scientists are trying to give some choices for people to live forever. There are several possibilities that could be done to cheat death, from biology, digital, and spiritually.
1. Cryonics
Cryonics is the body's clotting mechanism in liquid nitrogen to a temperature of minus 196 degrees Celsius. Previously, the blood was given fluids cryo protectant to prevent ice formation in the cell. In this way, the body and the brain will remain durable.
Unfortunately there is no technology to revive the body undergoing this procedure. That is, how is limited do to the body. There are more than 250 people who preserved this way. These bodies waiting for technology that could raise them again.
2. Brain Emulation
Is a method of uploading the human mind and memory into the computer. That is, the human brain can be digitally copied into the computer. If the mind can be uploaded, which means that the mind can also be downloaded into the robot. Thus, human thought and memory can last a long time.
3. Cybernetics
Science has succeeded in creating artificial organs that are almost exactly the original organ. For example, artificial limbs belong to Oscar Pistorius, the first Olympic runners with two legs had been amputated a fight with normal athletes. Human amid hopes the creation of new tools to support life, perhaps an artificial heart that could last forever or other organs.
4. Nanobots
Nanobots are microscopic machines that are designed to shape and heal the body. Scientists have succeeded in using nanobots to repair the optic nerve in hamsters blinded by creating synthetic molecules.
When injected, the molecule will transform itself into fibers for nerve repair. Now scientists want to create little robots to be able to kill cancer cells.
5. SENS
SENS stands for Strategies for Engineered Negligible Senescence. The term was inspired by the lobster and the hydra that showed no signs of aging at all. The experts want to find a similar method to eliminate all age-related diseases.
To encourage the discovery of SENS, Methuselah Foundation offers cash rewards to researchers who could break the age record for the oldest rats. The record to date is 1819 days, not bad for an animal that has a life expectancy of less than 1 year.
6. Eternal Youth Telomerase
In human chromosomes, there is repetition at the end of DNA called telomerase. Each time a cell division, telomerase shorten and encourage cell will stop dividing and eventually die. The enzyme telomerase is found in the 1980s is believed to inhibit this process.
As a result, the aging process can be slowed or even stopped. The experimental results prove that old mice given enzyme telomerase become healthy again. Therefore, this enzyme is known as the eternal fountain of youth or youthfulness.
7. Cloning
Cloning is an effort to create a duplicate or duplicates of living things. The scientists managed to do this technique to sheep and cattle. Efforts against human cloning could be done, but opposed by a global humanitarian organization.Through the cloning process, a new organism that is genetically identical can be made. Individual body cloned will match exactly with the original.
