Driving a cab definitely involves a lot of stress, according to taxi owner and driver Kathy Pavlofsky of Berkeley, California. "You never know who's getting in your cab, so you have to be constantly vigilant and expect trouble at any time," says Pavlofsky, who drives up to 16 hours a day and manages a fleet of five cabs. To deal with the stress, she goes to the gym and does cardio exercises and lifts weights several times a week. "I have to stay in shape to be able to lift customers' heavy baggage into and out of the cab," she says.
