Scientists may develop new biotechnologies to slow down the body’s aging process and vastly increase the length of the human lifesp an in the future. So the research is called life- extension research. Our lifespan is maximum 100 years or so, better ways to treat and cure diseases have made it possible for people to live longer on an average. But, life-extension research aims at making it possible for people to live much longer lives than we do today, not simply by treating or curing disease, but by slowing down the actual aging process itself. Some scientists estimate that we could live up to 150 years or more by intervening in the rate that we age.

a. Ageing Associated with Mitochondria

Mitochondira are unique components of a cell because they possess DNA of their own and replicate in a manner similar to the cells in which they are found. This DNA is a remnant of the ancient forerunner of the mitochondria which was a free-living bacterium. This study, which was conducted at the California Institute of Technology focused on mutations in the region of mtDNA that controlled the replication of the mtDN A itself . It was found that specific mutations in the control region would appear and proliferate within individuals as they age. This complements prior work that demonstrated that the amount of active mtDNA declines as an individual ages. It may be that the accumulation of the mutations such as those detected in this study are the underlying cause of this phenomenon.

b. Cryonics

Cryonics is the low-temperature preservation of humans and animals who can no longer be sustained by contemporary medicine, with the hope that healing and resuscitation may be possible in the future. Ideally, cryonics would allow clinically dead people to
