i would not want to live forever.based on your religious beliefs,is what happens after your death.my personal belief is your either six feet under or baked.but if we lived forever,it would disrupt the natural order of life,there is no life without death,could you imagine if people didnt die?we already have a population problem.it also bothers me how some people celebrate death,spending thousands on funerals.i know i dont want a bunch of bad dressed people with lame flowers staring at my dead body when i die.as far as the world ending,that will begin when natural resources begin to run dry,which they will,not for a long time im sure,but then comes chaos,and wars over the last of the resources,and there is evolution,we are a species and could become extinct,or we could keep evolving.and thats my opinion.im new here by the way,high to everyone!and thank you for smoking:stoned:
