Joey jojo, not sure where your stats come from. I watch sport a lot and I have never seen a fit sportman/woman drop from cardiac arrest until recently. One of the announcers commented on one case. He had been in broadcasting for twenty years and had never seen anything like it.
It has definitely happened in the UK way before Covid, tragically to a couple of young, fit footballers.
