It seems that the mystery is finally cleared up.
During these days Luffy is being the protagonist of many One Piece anecdotes, since, after all, the captain of the Straw Hats has proven to be smarter than he looks at the same time that we have also been able to verify that other aspects of the character. That yes, if there is a mystery that surrounds the rubber boy, that is without a doubt his age in a recent chapter.
Under this same premise, it must be said that One Piece is currently in the Egghead Island arc, where the members of the main crew have met with Jewelry Bonney, thus giving rise to the fact that we have been able to see luffy 70 years old Due to this character’s ability to change the appearance of othersto make them look younger or older.
They find meaning in old Luffy’s appearance in recent One Piece chapters

Luffy’s family has two gods, which the world government must face
And under this same idea, and in order to escape from a Pacifist, we can see Jinbei as a child and Luffy and Chopper as the elderly, thus giving rise to Luffy’s appearance being somewhat careless as an old man, which marks a great difference with what is seen in Oda’s sketches that shows him at 40 years old, very similar to Shank and 60 to Garp. And it is that all this could be due to the fact that the Gear exhausts him too much at the same time that the fact of not yet being the King of the Pirates would distance him from the good life.

This is something that can be seen in the tweet above, since if Luffy manages to become the King of the Pirates, he will reach what is known as the good time line, while if it doesn’t, it will look worse. Time will tell how this character’s career ends. For the rest, remember that the next one piece chapter is 1065in which more details are expected to be revealed.
