Seriously these questions are so loaded. and your thesis is bullshit because you want a certain outcome. Don't be so biased and ask questions that still pertain to the thesis without being so one sided and you'll get better results.
Instead of asking How are you physically? why not List other activities you do.
instead of Are you currently unemployed? Why not Employment status.
instead of Do your physical/personality attributes play apart in deciding what class/race/faction you play? why not Why did you choose your race class role.
instead of Are you above the age of 20 and still living at home/with relatives? why not Do you Own, rent or other. and ask the age in a seperate question.
You'll get more information this way.
