User blog comment:Sargenttacos115/Natsu and Gajeel age Theory/@comment-86.150.238.2-20140929000817

I think when he was a kid since Natsu was raised by a dragon that maybe Igneel slowed his aging during the time when he was a kid to make it Centuries but to Natsu it seemed like a couple of years. I have also come up with a theory that maybe when natsu went to sleep the night Igneel left that he had actually cast a spell on him to have him sleep for an extended period of time (just like the island arc) as a way to protect his son. That is just my theory though.
