One problem with life expectancy is how countries report infant deaths. USA has different standards than most countries, which as a result, it hurts their health statistics. > well-known issue with cross-country comparisons of infant mortality is possible reporting differences for infants born near the threshold of viability. Extremely preterm births recorded as a live birth in some places may be considered miscarriages or stillbirths in other countries (Golding 2001; Graafmans et al. 2001; Sachs et al. 1995; Wegman 1996). Since survival before 22 weeks or under 500 grams is very rare, categorizing these births as live births would inflate reported infant mortality rates (which are reported as a share of live births). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4856058/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4856058/
