Why does the United States have a lower life expectancy compared to other developed countries despite its high healthcare spending?

The United States spends nearly twice as much as any other developed country on healthcare but has a lower life expectancy. This could be due to various factors not fully explored in the script, but it's noted that the U.S. has a unique health system and other social determinants of health that may contribute to this discrepancy.

How does education level correlate with life expectancy?

There is a positive correlation between life expectancy and education level. Education is actually a better predictor of life expectancy than wealth, as it can raise IQ levels and improve executive functioning and cognitive abilities, leading to better life choices.
