Controversial theorist Aubrey de Grey insists that we are within reach of an engineered cure for aging. Are you prepared to live forever?

According to Reinhard Stindl, of the Institute of Medical Biology in Vienna, the answer to this question could lie at the tips of our chromosomes. In a controversial new theory he suggests that all eukaryotic species (everything except bacteria and algae) have an...
