Hi Paul,
Interesting article but tells us nothing we don't already know.
If the ratio of women to men is so different it has to be biological, but then the variables are enormous making
it possibly many years before they would get any breakthrough in their understanding

.
Personally I'm not sure if there is any value in finding out because there are still men with it, and what value would it
be to them? Far better to spend time on a project that would benefit all.
I certainly didn't expect to get RA, OA yes, but then I thought I'd never get ill

How ignorant can that be!
