Well, if this is the so called "Elixhr" of life...that's just going to make things worse! Humans were not made to last forever! Immortality is just not possible. If it was, imagine how terrible our world would be! Sure, good people could have access to it, but would you want someone like Stalin or Bin Laden to get a hold of something like that? (Yes, I know they're dead, but you get the point.)
Plus, our world is already over-populated. We can hardly feed all the people in the United States, much less the world! Name one country that has virtually no problems feeding ALL of its inhabitants. There is none. Scientists are already worried that if the life span gets any longer, that there could be a whole bunch less resources to feed those being born each day. Death is natural, disease is natural. It is unfortunate, but that's how it is been! Every religion has spoken about Death and its importance. People should enjoy life if they can, and just accept their fate.
