London: Superstar Robert Downey Jr has defended his past drug addiction and says it's "perfectly normal" for people to become "obsessive over something".

The 'Iron Man' star-struggled with substance abuse in the past, reported Contactmusic.
"For some folks it's just a function of age. It's perfectly normal for people to be obsessive about something for a period of time, then leave it alone," he said.
The 49-year-old actor, who also spent time in jail after breaking out of court-ordered rehab, finally recognises the ways in which addicts can successfully tackle their issues.
"Job one is get out of that cave. A lot of people do get out but don't change. So the thing is to get out and recognise the significance of that aggressive denial of your fate, come through the crucible forged into a stronger metal. Or whatever.
"But I don't even know if that was my experience. It's funny: five years ago, I would've made it sound like I'm conscious of my own participation in seizing the similarities.
But so many things have become less certain. I swear to God. I am not my story," he added.
