It's really interesting actually, worth doing.
I found lots of the questions relevant to tom boy teen me, although I never thought I could actually really be a boy, because such thoughts didn't really exist in the 70s/80s. Well, I certainly never came across them.
Anyway, I'm glad they are doing more research on this. I hope lots of people do it, from all backgrounds.
