I'm going to have to check out that issue of Playboy. I haven't looked at one, I mean read one, in years.
I view character defects as behaviors I want to improve in myself, and there is always room for improvement (and if I run out my wife could probably name a few more if I asked her). For example one area I've grown in, is that I no longer use my middle finger to signal to other drivers.
Don't get hung up on the term "character defects" I see it as a reflection of language from my grandmother's generation.
By the way, I've read Undrunk: A Skeptic's Guide to AA by A.J. Adams and would recommend it. It helped me decide to give AA a try and I'm glad I did.
