 On a rural road, winding through autumnal trees, a solitary cyclist heads down hill; he seems to resent it when he has to steer to the side to let a convertible go past. Several hundred yards ahead, the car stops for a red light, and the driver lights his companion s cigarette. She smokes, leans over to kiss the driver as her hand with the cigarette extends beyond the car s window. The cyclist approaches, grabs the cigarette and looks back at the car s passengers with a sneer. He should have known, however, that smoking can be hazardous to your health.
