We have a huge amount of data around physical size being inversely correlated with lifespan. The bigger you are, no matter what drives it - height, muscle mass, body fat, etc. - the lower your life expectancy is.

Obviously lots of other factors, but it does help explain part of why we see much of the most developed portions of Asia at the top of the list.

Switzerland is an interesting counterpoint, though - average height there is taller than most of Europe - though their obesity rates are about half of that of the European average.
