Sometimes numbers are just weird, they do not always act like we think they should. I was in a small office, 10 people back in the 1980s 2 guys 8 women, 6 of the women had cancer all discovered over a 3 year period.
Statistically, it’s the type of cancer under the definition of ‘cluster’ which merits the attention.
Luciano is apparently the first person to put it together and still no one is investigating.
As I wrote in another comment, if this was a mere 10 cases of ‘the virus’ we’d be seeing a horse of a different color.
