It can soon become possible for humans to live up to 800 years with the latest scientific breakthrough.

Researchers at the University of Southern California said that they managed to extend the lifespan of a strain of yeast fungus that can live 10 times longer than normal.

Valter Longo, the leading researcher of the study removed two genes RAS2 and SCH9 within the yeast's genome, that is responsible for aging in yeast and cancer in humans and put the baker's yeast on a restricting diet that extended its lifespan enormously.

Longo claimed that in spite of the difference between humans and yeast cells, this method is applicable to the same breakthrough in science of human longevity. He also said that though they were far from making people live till 800 years, it is quite possible to improve people's health and extend human lifespan to 120 years now.

The upper limit of human lifespan is now considered to be 125 years with just a few people managing to live that long.

Robin Holliday, a British gerontologist said that the claim that the possibility of humans to live up to 1,000 years may come from the future technology, where vulnerable parts of the body would be replaced and this would make a person live even longer.

Longo said that his scientific experiment proved that aging is genetically programmed and human lifespan can be altered to make people live much longer.
