(Sometimes the most interesting stories are real. This is as close an approximation of the conversation as I could get.)
"I'm sorry, but can you turn the air-conditioning down a bit?" she asked, leaning forward to the open glass window between passenger and driver.
He turned down the radio, and she repeated her request. He reached around the window, and flipped a switch.
"Thanks! I'm just not really dressed for the weather, I guess," she said.
"I really enjoy the air-conditioning, you know?" he responded. "The summer is good because in the boroughs, I roll down the windows and breathe the air. At the airport, in Manhattan I roll up the windows and breathe the air-conditioning. The smoke, all the smoke, I breathe it all day; at night, black stuff comes out of my nose."
"Oh my god, that's terrible!" she said.
"If I keep doing this another five, ten years, I will die of the lung cancer," he stated matter-of-factly.
"Oh, don't say that! That's a horrible thought!" she answered, shocked.
"It's true ... it's modernization, all of the smoke, the carbon monoxide from the cars, the buses ..." he trailed off for a moment.
"I grew up on farmland. Do you know that until the fourth grade, I didn't have shoes? Every day we walked to school -- two miles, two miles there and two miles back. There were no automobiles, just sometimes horses with carts would pass. Along the river, sometimes there were ships, they ran with steam engines.
"Everything we ate was organic, without manure or anything to grow it. My brothers and I would climb trees and eat the fruits. We swam in a pond. Now we are spread out, my brothers live in Sudan, in England, in Japan and Canada, but every three or four years we have a reunion at the farmland. We haven't destroyed it, it's part of our inheritance. The children all come and they love it. The roads are now bigger, but it's still not modernised.
"Where I grew up, I didn't get any shots but for smallpox," he continued, and rolled up his sleeve to point out the scar. "Nobody had cancer or heart disease or diabetes. In New York everything is modernised but people get cancer and diabetes and heart disease."
He talked for a few more minutes until she reached her stop. She could think of nothing to do to assuage his fears but give him a big tip.
