Fall Out Boy - 27 Lyrics Meaning

I think 27 is talking about Pete himself because the lyrics say,"my mind is a safe and if I keep it then we all get rich" and if he keeps his head together then they can make money off their songs since he writes all the songs. And after that he says "my body is an orphanage we take everyone in" I think this means that Pete helps produce all these bands. And at age 27 Pete was having a hard time, with Ashley and his fame. He was close to joining the "27 club" which is the group of famous musicians that have died at 27, Pete almost committed suicide at 27. which leads to my next interpretation of the line "Doing lines of dust and sweat off the last night's stage just to feel like him." Him is probably one of the musicians apart of the 27 club. And since he was going through such a tough time he used drugs to make him feel better "And I want it so bad I shoot the sunshine into my veins I can't remember the good old days."
