Well, if you graph his substance abuse over time SA/T I believe he reached a saturation point in the early 90's s=1991 therefore, in youth his faster metabolism (FM) + lower saturation (LS) = more intelligable speech. His older self has a higher saturation (HS) and slower metabolism (SM).
His speech had been degraded by the late 90's so logically SA/T+SM+HS= obscenity laced babbling on mtv reality show. (OLB+MTV.)
