But “dying young” in Swedenis very different
from “dying young” in Burundi
So, no,
all Burundians do not live 31
years shorter than Swedes
“To live long” in Swedenis almost the same as
“to live long” in Burundi
Life expectancy… is an average
… is low when child-deaths are common
-Most Burundians get older than 50-Some die in childhood
-It is low in Burundi not because all die a bit earlier
-But because some die much younger
