When you think about it, Lungs and other organs are just machinations of their own, with Gajeel's case, he can pretty much ironized and add magic to give them unique abilities very much like constructing his own machines, via Iron Lungs, if he accidentally breaths in the poison then he can simply breath it out, that is what must be happening. And sounds like MBP needs organic lungs to infect instead of none organic ones.

Listen, I'm tired and this is getting annoying and I have a million better things to do than to explain things logically and I am on my last day of vacation so could you do us both a favor and just end it here? Thanks your a pal.
