How long would you want to live as a human if you stayed in perfect health?

Forever. A lot to see, a lot of places to go?

I wouldn't have enough money to do that. But if I did, I suppose I'd want to stay around as long as the money lasted. I might seriously consider living in Brigadoon, where my life isn't any longer, but every day it's 100 years later, as long as I could get an update on what happened during the 100 years. I might pick one day every 10 years instead, because catching up on 100 years in one day might be a bit too much.

Aw, living indefinitely in the same body would be boring. If I had to live hundreds or thousands of years, I'd want to be a Time Lord. I think regeneration would be pretty cool. And being a woman, I'd have more natural control over what my new body looked like. :)

. If the evil ones who have created genetically modified corn and soy beans, etc: keep up their messing with nature, the human lifespan will soon be going backward at 100 MPH. .

The longer you live the more likely you are to become trapped. I wouldn't mind dying at about 80 or so, though since thats so far off I know my opinion will change on that in a few years.

Awesome.

If they keep showing garbage like reality TV in the future, not very long.

I'm good with the way it is now. Life is way to hard to want to drag it out even longer.

perfect health? forever
