The last of Frank Sinatra's four wives will be buried next to her famed crooner husband Tuesday after a public memorial service in the desert near Palm Springs. Barbara Sinatra died of natural causes at her Rancho Mirage home last Tuesday while surrounded by family and friends, according to family spokesman John E.
Since the beginning of One Piece, Luffy didn't show any interest in any women. He even acted like he didn't care at all to Boa Hancock who blatantly show interest to him. Because Luffy didn't show any particular interest in any women, the exact opposite of Sanji who falls in love easily.
It has been hinted by Oda multiple times how Luffy is shortening his life span by using gear 2 and also when he had 10 years drained from him in Impel Down. So if I were to decide on how he would die, it would be by protecting the people he loves and not by being killed by a pirate.
No, not directly at least. The fact that they both have the D initial means they are both from the D clan, so they are related in that sense. However, luffy is not roger's son, or grandson or nephew or anything like that. Luffy's father is dragon.
