I'd like to live a very very long time, so I can do great things and have as much of a taste of what earth as to offer to my senses and mind as possible.. but I wouldnt want to live forever.

I'd witness world wars 3-10.. all sorts of side catastropes.. and too many relationships of various kinds in my life will live and die when the other parties involved die.

Maybe if I adopted a less personal way of thinking about the mortality of friendships, relationships, family, and got used to the ugliness of mankind's way of existing and coexisting, I might not mind it so much after a while, but I think my emotional self would be too fragile to live more than a millenium or so, even if my body could.
