One piece theory-Smiles, The will of D., Devil fruits, OH MY! (how smiles are the key to understanding the story of one piece)

Oda has been hinting that smiles play a major role in the over all story of one piece for a very long time.

*People who carry the will of D. Smile at death *There are 6 known examples of this; Ace, Gol Rogger, Luffy, Sual, Law, Portgas Rouge. All with D. in their names and all smiled when faced with death. *People who carry the will of D. Smile ALOT in general *Doflamingo told disco on the den den mushi that the "age of smiles" was coming *Doflamingo called his artificial devil fruits "smiles" *SAD is the chemical used to make artificial devil fruits, saddness is the inverse of smiles *Doflamingo's jolly roger is a smile being crossed out laws jolly roger is a smile Smiles are on aces hat *Oda draws smiles all the time throughout the entirety of one piece, this includes but is not limited to, white beards ship and the human auction house. *JOY boy is left a message on the Poneglyph in fishman island, Joy is the emotion had when smiling *The letter D itself could be an outline of a smile, if flipped around

Because of the deep connection that Oda laid out between smiling and the will of D. and smiling and the production of artificial devil fruits it seems clear that smiling somehow, some way, is a critical plot element.
