I've just learned of this online survey. The notifier has a very high regard for Dr Chu. Read the preamble carefully, and don't start it if you don't think you can complete it in one session. Dr Chu provides this helpful advice: "You may want to look at the survey first, think about/ write down your choices, and then return to fill it out when you are ready. You may also choose to have someone else help fill in your answers for you after you have informed them about your choices."
