"you can see that people in some parts of the U.S. live as many as 33 years longer on average than people in other parts of the country, the researchers say"
That just can't be true.
That just can't be true.
In the UK there is a 24.2 year difference between the life expectancy for men in the Calton area of Glasgow and the national average. I think 33 years for the difference between longest and shortest expectancies in the US sounds about right.
By way of explanation:

[NB I don't follow football, come from a part of Scotland that has no real sectarianism and I married to someone from an Irish Catholic background - but I've seen enough displays of horrible bigotry towards Catholics to know it can be a serious problem, although it's not nearly as bad as it was]

With average life expectancy in the United States being around 78-79 years the quoted 33 year range seems reasonable.
