I beg to differ as if we were to judge purely based on this logic China and India would have probably also been at the top of the curve, which is not really true. Both of these countries greatly value family and it's quite typical for people to stay with their parents well into 30's and beyond.

What logic? I didn't say it's related to life expectancy, just that it'd a curious random fact about those two countries at the top. It might be related, or not, but I cannot say either way.

In fact, it would surprise me greatly if there was a single culture trait linked to life expectancy, instead I'd expect it to be a combination of vastly different things that make us get to the top.

Random fact: Did you notice that both countries' names end in the letter N? At least, their English spelling ends in N.

Oh cmon, while I think my statement is relevant I cannot tell whether it's (co)related or not. Those are very different topics and you are mixing them up together.

Life expectancy will definitely be a multi-variate equation. I don't know how much the family play the role. But, India and China with nourishment, clean drinking water, basic sanitation, pollution etc as other variables do not negate it.
