I would love to live to 120 or so, soley for the chance to see us go into space and colonize other planets. In fact, I seriously want to be one of the first people to colonize Mars. Depending on when that becomes a reality (most likely 30+ years from now) they're gonna need to see the effects of space travel and exposure to alien environments on older bodies. I'd donate my body for that cause in a heartbeat.

But to answer the original intent of the question, I would only want to live as long as I wasn't a burden on my family or society. Oh wait a minute, I guess I already qualify for that... :hmm:

I just want to grow old. I want grandchildren. I want to see my grandchildren have children. I want to hold hands in public with my husband when we're in our 80s. I want to celebrate 50+ years of being happily married. I want to welcome death as a new adventure, after I've had a full life.......

I'd like to live for as long as is (in)humanly possible. I don't relish the idea of not being around anymore.

There's so much to do in this world, I'd want to live forever. Inspired by Neil Gaiman's character, Hob Gadling.

long enough to know the answer to that question
