Would you like to live longer?

It seems to be that one day in the not so distant future scientists are going to be able to extend humans life spans from the average of eighty years to six hundred, or even more according to recent experiments. Of course that sounds unbelievable and even too fictional, but thinking about what these scientists have been able to do with some worms, yeast, bacteria and mice by extending their life span, there is no reason to think that one day in the future they are not going to be able to do the same with humans too. Think about this, if they have been able to extend a worms life span from one week, to eight times that, wouldnt it be possible to extend our average 80 years of life span to eight times that too?
