Note low road traffic accidents -- stop saying we are bad drivers! Women born in South Korea in 2030 are projected to be the first in the world to have an average life expectancy of above 90, a new study has found. In the United States, however, life expectancy is set to rise more slowly. This is due to a combination of factors including obesity, high maternal and infant mortality rates, unequal access to healthcare and relatively high homicide rates. By 2030 lifespans at birth for American men will be comparable to those of Czech men (under 80) and American women will have life expectancy similar to those in Croatia and Mexico (under 85). South Korean women will soon outlive us all. What's their secret?
