A few summers ago in the southern Indian city of Bangalore, an economist named Anant Nyshadham was heading to lunch with some executives at a garment factory.
"We walked through the factory floor on the way to the canteen," he recalls. "And I thought, 'Wow, this is really hot.' "
And this is a man who grew up in the state of Georgia. "But you know, I don't think I'll ever get used to the heat and humidity [there]," he says, laughing. "And India is on a different level."
