Well, we know for sure that Luffy's life is dramatically shorten, due to Ivankov's Healing Hormones, which take off 10 years of his life, and Gear Second, shorten his life, before the timeskip. But exactly how much Gear Second take off Luffy's life, I don't know. After the timeskip, maybe Gear Second don't have any effect on his life now, because he seems to use Gear Second for everything now. Or maybe he just don't care about his death.
