IMHO the answer to your question is no.
My baby daughter will spend an hour trying to pull down the bumper pad in her crib so she can see us when she first wakes up in the morning. Is she obsessed at the age of 7 months?
My wife will spend 2 hours doing her hair. Is she obsessed?
My son will spend 4 hours trying to master the guitar solo for his favorite song. Is he obsessed?
Talk shows have really wrecked society and the way we look at each other IMO.

Here's the real question I think....

If someone spends a lot of time on an activity that is by its very nature time consuming can they easily be labeled obsessed or addicted?
YES!!!
Is the world label crazy?
YES!!!
If you were posing a character in a scene could you really pose just one finger and then leave it alone for two days and then come back and pose just one more finger etc?
Would you not be labeled a procrastinator or lazy then?

Labels...BAH.
