User blog comment:Sargenttacos115/Natsu and Gajeel age Theory/@comment-108.181.231.105-20140318014757

My theory is that because dragons supposedly don't age very much and natsu only remembers ever living with Ignial his dragon that he aged along with him and that only after they became separated is when natsu began to age normally, which is why he would be over the age of 80 this would also apply to gajeel and Hindy.
