i believe that what was stated in the anime, but rather unclear, again i could be wrong, it's been a while
i do distinctly remember lucci saying luffy;s organs are rubber as well, and are able to withstand gear 2nd
I'm pretty sure he said it was shortening his life after he said that he's able to do it cause he's rubber. Could be bad subs though.
But it does sound like something Luffy would do. Getting stronger in order to protect his friends and family, not caring if it shortens his life.
