Do you ever think about the future and feel a little, sad that you're not going to experience it?

I think you may be watching too many sc-fi movies. I dont believe there will be any off those things you mentioned in the future. Think about how within just 100 years humans have shortened the lifespan of this planet. If we havnt killed each other over the last drop of oil or gas pockets left in the world then global warming will eventually take its toll and make the world a very uncomfortable place for any one to live. So if i were you Id be glad to grow old and die. The future looks pretty bleak love. Nice question though:)
