I am always wary of research that increases life span. It the world we are in, these technologies will be adopted by the rich, most likely be made exclusive and will further make the world an unhappy place to live, further increase inequality and further class based divisions in society. I am all for research into diseases and reducing suffering. But increasing life-span, more than current 'longest' records, is not a good thing for society, IMV.
