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. 

sesx is just a form of pleasure, when science discovers how the brain-computer generates pain and pleasure then we can simply experience super orgasms at the press ofa button

though this may have to be restricted or we would just lie back and experince intense pleasure until we starve
