Duff McKagan looks better today than he did two decades ago. Maybe its because he's cleaned up his act and knocked off the drugs? Now, McKagan is a family man to model wife Susan Holmes and father to the couple's two girls. He keeps his body fit thanks to kickboxing and he keeps mind nimble by blogging and running his own financial management firm geared toward the music industry. Remember guys: ladies might love your looks, but a big brain is the biggest turn on of them all.
