It would be useful to know why you are asking these questions and what you intend to do with the responses. It would also be appropriate for you to tell us about the ethical issues involved.
Did you really want people to reply to this thread with their answers? [edit: I have just seen that you are happy with an email reply. My suggestion about an online version still stands, though.] I can't imagine many people wanting to do that, whereas more people might be willing to fill in a questionnaire that is set up via Survey Monkey or something similar.
You might get more responses if you can ensure the questions are clear and free of errors. Do you have a colleague or a tutor who could help with proof-reading this questionnaire? It could be worth piloting the questionnaire too.
Good luck with your data collection.
