actually, strangely, mexico is now the most obese country in the world. i should have checked that before posting; i thought it was obvious. but, no - they've recently even passed the united states as most obese country, flat out.

so, it could actually be relatively bad there, then, and you might see a mortality curve that it's actually skewed a little younger.
