A decade ago my Polio scar was itching... I asked my doctor about it and she didn't have a clue as to what the scar on my shoulder was... I never went back. hehSon, don't kid yourself.
If polio was as rampant today as covid was the same people would be calling it a government conspiracy and refusing the vaccine.
Bayview and Eglinton in Toronto. My old neighbourhood. I worked at the Shell and the Esso station when I was a kid, Karbelt speed and custom was between the car wash and Esso.
