did you ever hear the saying 'the last gallon of oil in this world will be burned by an engine of a tank' it means a finite resource will be fought over to the last drop. in a old dark cold entropic universe unraveling by the molecular level its only a matter of time. you can run you can hide you can try and cheat it but you would only end up in complete darkness and you better hope you dont have a soul because if you did the exit door has long since been closed and you do get you're wish to see what forever is :)
thats the Immortality you get.
what type of 'life' do you think will be the last left ? :)
