I knew several at university and many in the medical field and the energy sector. All together a dozen or so and my grandmother.
“I knew several at university “
Next time you troll, try to at least use the same verbiage we do in “the States.”
First it was "a couple of dozen", now it's " A DOZEN", and just WHAT has your grandfather got to do with anything? Is he still alive,living in RSA?
You're so like a faaaaaaaaaaaaaaaaaaaaaaar lefty!
Keep it up; you're proving that you are far out of your depth.
