Maroon 5 guitarist James Valentine is beginning to feel his age - he can no longer stay up all night partying if he has an early start for work. The 29-year-old star laments the loss of his youth in a post on his MySpace webpage, where he reminisces about his days as a wild rocker. He writes on the social networking site, "Tomorrow we have to get up at 5 a.m. for GMA (U.S. talkshow Good Morning America). "I shouldn't go out now. I used to be able to get up and do those morning shows after being out all night. I remember doing the Today show and taking a nap on the floor in our dressing room, which was basically the space outside of the anchor's dressing rooms, and (The Today Show host) Matt Lauer having to literally step over me. Ah, those were the days."
