I'm just speculating here, but based on the questions and how they related them to desire and actualization, I'd say they are attempting to determine:
How much self control each individual has.
Whether or not participants use illegal drugs.
What if any activities non smokers have replaced their cigarette habit with.
Level of libido.
Closeness with family.
How physically active each individual is.
How social interaction effects addiction.
What that all adds up to I am not sure.
I would like to agree with you but as i have not read the questions the approved ones were sent I am out of a serious opinion but I am wandering what Rolygates could tell to us, he created this thread but he is as silent as a body in the dead house
