Not entirely true, e.g. deaths from natural disasters have been on a steady decline over many decades despite such disasters becoming more common and more destructive. In general our ability to continue improving human life expectancy has seemingly defied the odds - even in 2022 despite covid and everything else, average life expectancy is expected to improve on 2021 in most countries (including the good ol' U S of A). It does feel a bit like quantity over quality though.
