Rocker Iggy Pop insists it's much harder to relax now he is clean and sober - because he used to rely on smoking a joint to feel good. The 59-year-old has adopted a healthy lifestyle, and claims the clean-living way of life is much harder to maintain. He tells Spin magazine, "To feel good when I was 21, all I had to do was to smoke a joint. "Now I have to turn off my phones, do tai chi for an hour, drink a strong cup of coffee, and stay away from bad people, so I can feel good for an hour or two, knowing when it ends, I'm gonna feel like the miserable 59-year-old prick that I actually am!"
