I've just completed Darren's survey request which appeared on this site a short time ago. I would encourage you to have a look and fill it in. It doesn't take too long and I have to admit, it was most interesting. I found some of the questions a bit difficult as my diagnosis was a long time ago, so I had to get my thinking cap on.
I think anything like this, which helps train the people who look after our health and welfare, very worthwhile. Go for it.
Best wishes, Bill
