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. 

I'm not about to read through all responses that have been made, but I assure you it's possible to live up to about the age of 600.

There is in fact a gene in cells that causes them to die after a certain number of reproductions, and scientists found a way to shut off this "timer" on life. Cells cease reproducing once they have no more room to expand, which is why you only grow new skin once old skin has shed off and made a place for the cells to grow over. For this reason by disabling the gene you can cause your cells to go on reproducing, your brain to go on functioning, and your heart to go on beating for years. They tested it in earth worms and they noticed that every worm who recieved the gene therapy lived about 8 times longer (which is why they get the number 600 years). Not only this, but unlike normal worms which become slow and stupid as they age, these worms remained very active until the day they died.

I don't know the exact cause of the death in the worms, but whatever it was, it was something sudden and predictable enough that every worm died around the same time. Also, the worms were perfectly healthy one day and dead the next. If you live to be 600, expect to randomly and suddenly die one day with no warning. Unless by then scientists have figured out what causes that sudden death, in which case try to avoid it =P

Lots of people think that living forever would be boring, but I'd personally like the idea. I understand all the "Your friends will die long before you" and "You'll do everything there is to do in life and still be alive" thing, but I'd still enjoy it.
