Forum:One Piece Ending

Is it just me? Personally, I really love one piece, and it's the greatest and most epic anime I've ever seen. It's filled with everything that you could ever wish for in an anime, but what bugs me is that I have this feeling that Oda-Sensei will make an unexpected ending in one piece. Remember that when Roger discovers that he has an illness and can't be cured anymore, he surrendered himself at the marines. I think that when Luffy finally claims the "one piece" he's been looking for and finally proclaim himself as the pirate king, he'll also die. Because on Impel Down, remember when Emporio Ivankov helped recover from being poisoned, that his life would be shortened by 10 years?

ANYONE PLEASE TELL ME THIS ISN'T GOING TO HAPPEN >.<
