How to live forever?

And by forever I mean at least 200 years.  Maybe 1000 if I'm lucky.  These anti-aging supplements only do so much to prevent oxidative damage.  Growth hormone injections might keep you going for a little while.  Beyond nutrition I'm looking for a way to make DNA ignore that cells have to split a limited number of times in one life.  I don't want my cells to stop splitting, but I also don't want cancer.

Yeah, gray goo sucks :/  I guess I'll have to live in space, traveling around at speeds faster than light, fighting alien fleets, etc. while powering myself through... some future technology that I won't give any more to the nanomachines than they need (of course, they could develop the same technique I use and then rebel against me, but it's rather unlikely).
