He's exaggerating. Even in Africa most countries have a life expectancy over 30 (http://en.wikipedia.org/wiki/File:Life_Expectancy_2011_Estim...), at least according to the CIA World Factbook. Even then in most African countries life expectancy averages are cut short because the high number of HIV infections.
