Every body got covid, page-93

it did mention lower aged population though -

''1. Younger population: Africa has the world's youngest population, with a median age of 19 years. Older age is a major risk factor for severe COVID-19 outcomes, so Africa's youthful demographics helped reduce mortality[1][2].''

and a lower population age - skews life expectancy - as does an older population as does WAR

war will drop a life expectancy like a rock in a dunny
