Also, I remember reading when I was young that NOFX quickly abandonned the "drugs/alcohol/sex" ethos and become quite healthy people despite having the opposite branding.
It hasn't exactly been a clean path. Fat Mike has been on and off through the years and they never stopped singing about doing drugs. That said I think they are vegetarians and otherwise relatively health conscious.
It also mentions how instead of drugs, they do yoga and get massages.
No mention of their current sex life.
