I just thought it was because there were more key workers who are BAME. I also think it might depend on the make up of DNA, you can have someone who is half Asian, quarter, 3/4.
I don't think it's diabetes because lots of people have this irrespective of their DNA.
It can't be obesity, as lots of other people are obese.
Maybe it's being BAME, key worker, obese and diabetic cases.
