barryt,
You could choose to believe "everything we have been told by medical scientists and our governments, then they SHOULD BE HALF DEAD"
Which is fine except, there are contradictions within the establishment, fake news if you wish.
You could also add India into the mix, 1.38 billion people, the majority living in (very) crowded cities but with a death rate roughly a seventh of South Africa's, go figure, damned if it makes sense to me.
Average death rate for Covid varies from Yemen with 29% down to 0.0%, this is case rate not per 100,000; so even in the worst case scenario a long way from your half, live long and prosper but beware of self-fulfilling prophets.
