Pregnancy and gravity. Computer artwork showing how increasing body mass on the front of a woman's body during pregnancy - caused by enlarged breasts and the weight of the child - causes the centre of gravity (yellow and black) to move forward. This means there is more weight at the woman's front, which causes the body to curve forward, putting greater stress on the spine.
