It would take a team of mathematical obsessives to calculate the heat quotient of lanky and lovely Argentinian beauty Yamila Díaz. Not only is Yamila a bonafide supermodel, with all the scorch value that goes along with that designation, she is also a coffee-skinned Latina with the creamiest complexion any human could possibly have without melting into a puddle of milky sweetness. So, should the heat calculators assign Yamila a ten for profession and another ten for ethnic persuasion and then add the two together for her rating? Or are the numbers multiplied? Do they expand exponentially? What kind of bonehead harbors any such thought when the bikini-clad form of a girl who looks to be Salma Hayek’s better-looking sister is available for contemplation?
