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. 

@ OP

I'm serious about this. Here is what you do: excel in school, go to an Ivy League College and study finance, become a wallstreet investor/broker, basically earn as much money as you can. eat healthy, stay fit, live at least for another 40 years.

once the tech is available, in 40 years, you will have the financial means to buy the tech to extend your life.
