According to a new study out of Duke University, being pregnant is so tough on a woman's body it's like running a daily marathon.ย Your body is working so hard and needs so many calories it's like you're an endurance athlete.
They also found that pregnancy maxes out the body's energy . . . if it were any tougher, it wouldn't even be physically possible.ย In other words:ย Just give that pregnant lady your damn seat.ย
