Thank you for your reply and insights.
I know my english isn`t perfect, I am not a native english speaker (I am from Slovakia). I will try to correct all my mistakes.
I used SL very short time, my computer is not very efficient. I consulted my questionnaire with a few users of SL.
I know that some people have more avatars and that`s the reason why I requested you to pick the one you use the most.
Question 27 is about food and question 29 is more general, it includes also exercise, smoking etc.
Question 23 concerns you want to be better and better person.
I have no budget, no team of people and this research is one of my school tasks. I understand people can consider it as a low quality research. My possibilities are limited.
If you think some questions don`t fit to your avatar, reply "never", I know that avatars are virtual
I just want to know about self-care in SL, I don`t want to prove something special.
