"Women ....... 40% higher all-cause death rate, and men had an approximately 20% higher death rate"

I think you'll find that eventually there is a 100% "All cause Death rate" for all men and women alike..... I think there is some additional data (that adds some sense) missing here and this contradicts the overwhelming evidence that those in white collar employment (typically sitting) have on average a 3.5 year greater lif expectancy that blue collar (typically active) workers. There are far too many extraneous variable involved here to make such a simple deduction.
