Five Hearts

I propped my visor right over an open garden guide lying flat on the workbench because... well, interns probably need to study for captain exams eventually. There was a big diagram of an earthworm with arrows pointing everywhere, and one label said 'five hearts.' Five! I leaned in so close my brown hat brim almost brushed the glossy paper. How does something that skinny even fit five whole hearts inside? I clicked my harness strap against my chin and whispered, 'Uh, Cuh, do crew members really need five hearts, or is that just for worms?' Just faint static answered. I shoved a smooth gray pebble onto the corner so the page wouldn't flip.
