Phoned the m.s. help line recently - guy was very helpful - then I was asked to respond to a phone survey re how helpful I had found the advice. (my query was about m.s. and genetics)
First few q’s about the actual call - then I was asked for my age - then my ethnicity (not sure where ‘white and Welsh’ fit in!) - then asked about my sexual orientation - then I was asked about my gender - then I was asked if I was binary/non-binary.
I seem to recall something about binary numbers in my old primary school but I must admit the last question confused me a bit.
Same thing happened at the optician - asked to fill a form in asking all sorts of personal questions - not easy when your vision is blurred following the (dare I say it) the puff test.
