This is the reason I don't take anything stronger than Advil or whiskey. I saw too many 'tough' athletes growing up succumb to painkiller addiction. There should be more awareness to the addictive properties of the painkillers, especially before they're prescribed.
As for Karo, it's too bad, I enjoy watching him fight. I'd still pay good money to see him matchup with Matt Hughes.
He is pretty fun to watch. I will always remember that sick throw he had on Diego Sanchez! That was awesome!
