As with all these claims I also don't know how they can possibly make sense in any real way. Americans drink more coffee than us so should, in theory, last longer than us, but obviously don't because of other factors, like gunshots. How you weigh all the possible different factors looks like a near impossible feat to me.
The claims about red wine are equally incomprehensible to me.
Still, I am ridiculously self-satisfied that the only hot drink I have is coffee.
I will also at great sacrifice to myself, persevere with red wine.
