Big life threatening disease Cancer has the ability to shun down DNAs ability to repair itself. Our DNA is our identity. Cancer causes mutation and cells behave abnormally.
Surgeons and scientists together are working on a technology to restore the ability of DNA to repair itself. Once DNA is powerful enough, it can itself debilitate Cancer and such mutation agents.
This technology will surely increase our life expectancy by a huge margin , maybe to about 150 years on average .
