Cora lay back on her beach chair, halfway asleep. She stretched her arms above her head, and ran a hand over her trim belly. “It's almost getting to the point where it's strange when my belly's small,” Cora thought to herself, “Never thought I'd get used to carrying around a belly that big.” But she didn't have to think about it for a while, she was on leave, her bio-electrical collector was about five hundred million miles away, and the only time her belly would get big was when she ate too much at the buffet.
